Paweł Chmiel 34138a59b9 clk: exynos7: Mark aclk_fsys1_200 as critical
This clock must be always enabled to allow access to any registers in
fsys1 CMU. Until proper solution based on runtime PM is applied
(similar to what was done for Exynos5433), mark that clock as critical
so it won't be disabled.

It was observed on Samsung Galaxy S6 device (based on Exynos7420), where
UFS module is probed before pmic used to power that device.
In this case defer probe was happening and that clock was disabled by
UFS driver, causing whole boot to hang on next CMU access.

Adam Ford 379c9a24cc clk: imx: Fix reparenting of UARTs not associated with stdout
Most if not all i.MX SoC's call a function which enables all UARTS.
This is a problem for users who need to re-parent the clock source,
because any attempt to change the parent results in an busy error
due to the fact that the clocks have been enabled already.

  clk: failed to reparent uart1 to sys_pll1_80m: -16

Instead of pre-initializing all UARTS, scan the device tree to see
which UART clocks are associated to stdout, and only enable those
UART clocks if it's needed early.  This will move initialization of
the remaining clocks until after the parenting of the clocks.

When the clocks are shutdown, this mechanism will also disable any
clocks that were pre-initialized.

 - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
   issues with missing resources and unnecessary deferred probe

 - omap5 clocks are missing gpmc and ocmc clock registers
 
 - pci-dra7xx now needs to use builtin_platform_driver instead of using

 There are also few minor non-urgent fixes:
 
 - soc init code pdata_quirks_init_clocks should be static
 
 - ti-sysc has few unneeded semiconon typos
 
 - ti-sysc can use kzalloc instead of kcalloc for a single element

first, and checks clk_init_data.parent_names[] before
clk_init_data.parent_data[] and clk_init_data.parent_hws[], leaving the
latter uninitialized doesn't do harm for now.  However, it is better to
play it safe, and initialize all clk_init_data structures to zeroes, to
avoid any current and future members containing uninitialized data.

Remove a few explicit zero initializers, which are now superfluous.

Some of the RCGs could be always ON from the XO source and could be used
as the clock on signal for the GDSC to be operational. In the cases where
the GDSCs are parked at different source with the source clock disabled,
it could lead to the GDSC to be stuck at ON/OFF during gdsc disable/enable.
Thus park the RCGs at XO during clock disable and update the rcg_ops to
use the shared_ops.

JC Kuo 54443ef6f5 clk: tegra: Add PLLE HW power sequencer control
PLLE has a hardware power sequencer logic which is a state machine
that can power on/off PLLE without any software intervention. The
sequencer has two inputs, one from XUSB UPHY PLL and the other from
SATA UPHY PLL. PLLE provides reference clock to XUSB and SATA UPHY
PLLs. When both of the downstream PLLs are powered-off, PLLE hardware
power sequencer will automatically power off PLLE for power saving.

XUSB and SATA UPHY PLLs also have their own hardware power sequencer
logic. XUSB UPHY PLL is shared between XUSB SuperSpeed ports and PCIE
controllers. The XUSB UPHY PLL hardware power sequencer has inputs
from XUSB and PCIE. When all of the XUSB SuperSpeed ports and PCIE
controllers are in low power state, XUSB UPHY PLL hardware power
sequencer automatically power off PLL and flags idle to PLLE hardware
power sequencer. Similar applies to SATA UPHY PLL.

PLLE hardware power sequencer has to be enabled after both downstream
sequencers are enabled.

This commit adds two helper functions:
1. tegra210_plle_hw_sequence_start() for XUSB PADCTL driver to enable
   PLLE hardware sequencer at proper time.

2. tegra210_plle_hw_sequence_is_enabled() for XUSB PADCTL driver to
   check whether PLLE hardware sequencer has been enabled or not.

Krzysztof Kozlowski 552418658a clk: socfpga: use ARCH_INTEL_SOCFPGA also for 32-bit ARM SoCs (and compile test)
ARCH_SOCFPGA is being renamed to ARCH_INTEL_SOCFPGA so adjust the
32-bit ARM drivers to rely on new symbol.

There is little point to share clock controller drivers between 32-bit
and 64-bit platforms because there will not be a generic image for both
of them.  Therefore add a new Kconfig entry for building 32-bit clock
driverss, similar to one for 64-bit.  This allows enabling compile

Krzysztof Kozlowski 4a9a1a5602 arm64: socfpga: merge Agilex and N5X into ARCH_INTEL_SOCFPGA
Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and
SoC-part.  Up to a point that N5X uses the same DTSI as Agilex.  From
the Linux kernel point of view these are flavors of the same
architecture so there is no need for three top-level arm64
architectures.  Simplify this by merging all three architectures into
ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries.

The side effect is that the INTEL_STRATIX10_SERVICE will now be
available for both 32-bit and 64-bit Intel SoCFPGA, even though it is
used only for 64-bit.

Krzysztof Kozlowski a01be32fcc clk: socfpga: build together Stratix 10, Agilex and N5X clock drivers
On a multiplatform kernel there is little benefit in splitting each
clock driver per platform because space savings are minimal.  Such split
also complicates the code, especially after adding compile testing.

Build all arm64 Intel SoCFPGA clocks together with one entry in
Makefile.  This also removed duplicated line in the Makefile (selecting
common part of clocks per platform).

Krzysztof Kozlowski 3b218baa74 clk: socfpga: allow building N5X clocks with ARCH_N5X
The Intel's eASIC N5X (ARCH_N5X) architecture shares a lot with Agilex
(ARCH_AGILEX) so it uses the same socfpga_agilex.dtsi, with minor
changes.  Also the clock drivers are the same.

However the clock drivers won't be build without ARCH_AGILEX.  One could
assume that ARCH_N5X simply depends on ARCH_AGILEX but this was not
modeled in Kconfig.  In current stage the ARCH_N5X is simply
unbootable.

Add a separate Kconfig entry for clocks used by both ARCH_N5X and
ARCH_AGILEX so the necessary objects will be built if either of them is
selected.

Douglas Anderson 148ddaa89d clk: qcom: gcc-sc7180: Use floor ops for the correct sdcc1 clk
While picking commit a8cd989e1a ("mmc: sdhci-msm: Warn about
overclocking SD/MMC") back to my tree I was surprised that it was
reporting warnings.  I thought I fixed those!  Looking closer at the
fix, I see that I totally bungled it (or at least I halfway bungled
it).  The SD card clock got fixed (and that was the one I was really
focused on fixing), but I totally adjusted the wrong clock for eMMC.
Sigh.  Let's fix my dumb mistake.

Now both SD and eMMC have floor for the "apps" clock.

This doesn't matter a lot for the final clock rate for HS400 eMMC but
could matter if someone happens to put some slower eMMC on a sc7180.
We also transition through some of these lower rates sometimes and
having them wrong could cause problems during these transitions.
These were the messages I was seeing at boot:
  mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
  mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz

Jae Hyun Yoo 3536169f85 media: aspeed: fix clock handling logic
Video engine uses eclk and vclk for its clock sources and its reset
control is coupled with eclk so the current clock enabling sequence works
like below.

 Enable eclk
 De-assert Video Engine reset
 10ms delay
 Enable vclk

It introduces improper reset on the Video Engine hardware and eventually
the hardware generates unexpected DMA memory transfers that can corrupt
memory region in random and sporadic patterns. This issue is observed
very rarely on some specific AST2500 SoCs but it causes a critical
kernel panic with making a various shape of signature so it's extremely
hard to debug. Moreover, the issue is observed even when the video
engine is not actively used because udevd turns on the video engine
hardware for a short time to make a query in every boot.

To fix this issue, this commit changes the clock handling logic to make
the reset de-assertion triggered after enabling both eclk and vclk. Also,
it adds clk_unprepare call for a case when probe fails.

clk: ast2600: fix reset settings for eclk and vclk
Video engine reset setting should be coupled with eclk to match it
with the setting for previous Aspeed SoCs which is defined in
clk-aspeed.c since all Aspeed SoCs are sharing a single video engine
driver. Also, reset bit 6 is defined as 'Video Engine' reset in
datasheet so it should be de-asserted when eclk is enabled. This
commit fixes the setting.

Linus Torvalds 8b83369ddc RISC-V Patches for the 5.12 Merge Window
I have a handful of new RISC-V related patches for this merge window:
 
 * A check to ensure drivers are properly using uaccess.  This isn't
   manifesting with any of the drivers I'm currently using, but may catch
   errors in new drivers.
 * Some preliminary support for the FU740, along with the HiFive
   Unleashed it will appear on.
 * NUMA support for RISC-V, which involves making the arm64 code generic.
 * Support for kasan on the vmalloc region.
 * A handful of new drivers for the Kendryte K210, along with the DT
   plumbing required to boot on a handful of K210-based boards.
 * Support for allocating ASIDs.
 * Preliminary support for kernels larger than 128MiB.
 * Various other improvements to our KASAN support, including the
   utilization of huge pages when allocating the KASAN regions.
 
 We may have already found a bug with the KASAN_VMALLOC code, but it's
 passing my tests.  There's a fix in the works, but that will probably
 miss the merge window.

Linus Torvalds 7ac1161c27 Driver core / debugfs update for 5.12-rc1
Here is the "big" driver core and debugfs update for 5.12-rc1
 
 This set of driver core patches caused a bunch of problems in linux-next
 for the past few weeks, when Saravana tried to set fw_devlink=on as the
 default functionality.  This caused a number of systems to stop booting,
 and lots of bugs were fixed in this area for almost all of the reported
 systems, but this option is not ready to be turned on just yet for the
 default operation based on this testing, so I've reverted that change at
 the very end so we don't have to worry about regressions in 5.12.  We
 will try to turn this on for 5.13 if testing goes better over the next
 few months.
 
 Other than the fixes caused by the fw_devlink testing in here, there's
 not much more:
 	- debugfs fixes for invalid input into debugfs_lookup()
 	- kerneldoc cleanups
 	- warn message if platform drivers return an error on their
 	  remove callback (a futile effort, but good to catch).
 
 All of these have been in linux-next for a while now, and the
 regressions have gone away with the revert of the fw_devlink change.

Pull driver core / debugfs update from Greg KH:
 "Here is the "big" driver core and debugfs update for 5.12-rc1

  This set of driver core patches caused a bunch of problems in
  linux-next for the past few weeks, when Saravana tried to set
  fw_devlink=on as the default functionality. This caused a number of
  systems to stop booting, and lots of bugs were fixed in this area for
  almost all of the reported systems, but this option is not ready to be
  turned on just yet for the default operation based on this testing, so
  I've reverted that change at the very end so we don't have to worry
  about regressions in 5.12

  We will try to turn this on for 5.13 if testing goes better over the
  next few months.

  Other than the fixes caused by the fw_devlink testing in here, there's
  not much more:

   - debugfs fixes for invalid input into debugfs_lookup()

   - kerneldoc cleanups

   - warn message if platform drivers return an error on their remove
     callback (a futile effort, but good to catch).

  All of these have been in linux-next for a while now, and the
  regressions have gone away with the revert of the fw_devlink change"

clk: Add RISC-V Canaan Kendryte K210 clock driver
Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC.
This new driver with the compatible string "canaan,k210-clk" implements
support for the full clock structure of the K210 SoC. Since it is
required for the correct operation of the SoC, this driver is
selected by default for compilation when the SOC_CANAAN option is
selected.

With this change, the k210-sysctl driver is turned into a simple
platform driver which enables its power bus clock and triggers
populating its child nodes. The sysctl driver retains the SOC early
initialization code, but the implementation now relies on the new
function k210_clk_early_init() provided by the new clk-k210 driver.

The clock structure implemented and many of the coding ideas for the
driver come from the work by Sean Anderson on the K210 support for the
U-Boot project.

Linus Torvalds 28b9aaac4c This is all driver updates, the majority of which is a bunch of new Qualcomm
clk drivers that dominate the diffstat because we add support for six SoCs from
 that particular vendor. The other big change is the removal of various clk
 drivers that are no longer used now that the kernel is dropping support for
 those SoCs. Beyond that there's the usual non-critical fixes for existing
 drivers and a good number of patches from Lee Jones that cleanup a bunch of W=1

In the previous commit ("clk: qcom: rcg2: Stop hardcoding gfx3d pingpong

generalized in order to be able to reuse the same ops for more than just
one clock for one SoC: follow the change here in the MSM8996 MMCC.

AngeloGioacchino Del Regno 7cbb78a99d clk: qcom: rcg2: Stop hardcoding gfx3d pingpong parent numbers
The function clk_gfx3d_determine_rate is selecting different PLLs
to manage the GFX3D clock source in a special way: this one needs
to be ping-pong'ed on different PLLs to ensure stability during
frequency switching (set a PLL rate, let it stabilize, switch the
RCG to the new PLL) and fast frequency transitions.

This technique is currently being used in the MSM8996 SoC and the
function was assuming that the parents were always at a specific
index in the parents list, which is TRUE, if we use this only on
the MSM8996 MMCC.
Unfortunately, MSM8996 is not the only SoC that needs to ping-pong
the graphics RCG, so choices are:
1. Make new special ops just to hardcode *again* other indexes,
   creating code duplication for (imo) no reason; or
2. Generalize this function, so that it becomes usable for a range
   of SoCs with slightly different ping-pong configuration.

In this commit, the second road was taken: define a new "special"
struct clk_rcg2_gfx3d, containing the ordered list of parents to
ping-pong the graphics clock on, and the "regular" rcg2 clock
structure in order to generalize the clk_gfx3d_determine_rate
function and make it working for other SoCs.

As for the function itself it is left with the assumption that we
need to ping-pong over three parents. The reasons for this are:
1. The initial model was MSM8996, which has 3 parents for the
   graphics clock pingpong;
2. The other example that was taken into consideration is the
   SDM630/636/660 SoC gpu clock controller, which is ping-ponging
   over two dynamic clocked and one fixed clock PLL.

AngeloGioacchino Del Regno 53748348a5 clk: qcom: gpucc-msm8998: Allow fabia gpupll0 rate setting
The GPU PLL0 is not a fixed PLL and the rate can be set on it:
this is necessary especially on boards which bootloader is setting
a very low rate on this PLL before booting Linux, which would be
unsuitable for postdividing to reach the maximum allowed Adreno GPU
frequency of 710MHz (or, actually, even 670MHz..) on this SoC.

To allow setting rates on the GPU PLL0, also define VCO boundaries
and set the CLK_SET_RATE_PARENT flag to the GPU PLL0 postdivider.

With this change, the Adreno GPU is now able to scale through all
the available frequencies.

necessary to force retain mem, but *not* peripheral when enabling
this GDSC (and, of course, the inverse on disablement).

With this change, the GPU finally works flawlessly on my four
different MSM8998 devices from two different manufacturers.

AngeloGioacchino Del Regno 785c02eb35 clk: qcom: gdsc: Implement NO_RET_PERIPH flag
In some rare occasions, we want to only set the RETAIN_MEM bit, but
not the RETAIN_PERIPH one: this is seen on at least SDM630/636/660's
GPU-GX GDSC, where unsetting and setting back the RETAIN_PERIPH bit
will generate chaos and panics during GPU suspend time (mainly, the
chaos is unaligned access).

For this reason, introduce a new NO_RET_PERIPH flag to the GDSC
driver to address this corner case.

Daniel Palmer bef7a78da7 clk: mstar: MStar/SigmaStar MPLL driver
This adds a basic driver for the MPLL block found in MStar/SigmaStar
ARMv7 SoCs.

Currently this driver is only good for calculating the rates of it's
outputs and the actual configuration must be done before the kernel
boots. Usually this is done even before u-boot starts.

This driver targets the MPLL block found in the MSC313/MSC313E but
there is no documentation this chip so the register descriptions for
the another MStar chip the MST786 were used as they seem to match.

Tudor Ambarus 428d97e185 clk: at91: Fix the declaration of the clocks
These are all "early clocks" that require initialization just at
of_clk_init() time. Use CLK_OF_DECLARE() to declare them.

This also fixes a problem that was spotted when fw_devlink was
set to 'on' by default: the boards failed to boot. The reason is
that CLK_OF_DECLARE_DRIVER() clears the OF_POPULATED and causes
the consumers of the clock to be postponed by fw_devlink until
the second initialization routine of the clock has been completed.
One of the consumers of the clock is the timer, which is used as a
clocksource, and needs the clock initialized early. Postponing the
timers caused the fail at boot.

This allows fw_devlink to recognize clock provider drivers that don't
use the device-driver model to initialize the device. fw_devlink will
use this information to make sure consumers of such clock providers
aren't indefinitely blocked from probing, waiting for the power domain
device to appear and bind to a driver.

Enric Balletbo i Serra 8c18e927b1 clk: mediatek: Select all the MT8183 clocks by default
If MT8183 SoC support is enabled, almost all machines will use topckgen,
apmixedsys, infracfg, mcucfg and subsystem clocks, so it feels wrong to
require each one to select that symbols manually.

Instead, enable it whenever COMMON_CLK_MT8183_* is disabled as
a simplification. This would add few KB in the kernel image size but
will make the life a bit easier to the users, anyway you'll need to probably
enable all of them if you want to have proper support for that SoC.

The xlnx_vcu driver is actually a clock controller driver which provides
clocks that can be used by a driver for the encoder/decoder units. There
is no reason to keep this driver in soc. Move the driver to clk.

NOTE: The register mapping actually contains registers for AXI
performance monitoring, but these are not used by the driver.

If a driver registers a divider clock with a parent_hw instead of the

Alexandru Ardelean 324a810583 clk: axi-clkgen: replace ARCH dependencies with driver deps
The intent is to be able to run this driver to access the IP core in setups
where FPGA board is also connected via a PCIe bus. In such cases the number
of combinations explodes, where the host system can be an x86 with Xilinx
Zynq/ZynqMP/Microblaze board connected via PCIe.
Or even a ZynqMP board with a ZynqMP/Zynq/Microblaze connected via PCIe.

To accommodate for these cases, this change removes the limitation for this
driver to be compilable only on Zynq/Microblaze architectures.
And adds dependencies on the mechanisms required by the driver to work (OF
and HAS_IOMEM).

AngeloGioacchino Del Regno 292f75ecff clk: qcom: gcc-msm8998: Fix Alpha PLL type for all GPLLs
All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs
and not generic alphas: this was producing bad effects over the entire
clock tree of MSM8998, where any GPLL child clock was declaring a false
clock rate, due to their parent also showing the same.

The issue resides in the calculation of the clock rate for the specific
Alpha PLL type, where Fabia has a different register layout; switching
the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate
(calculation) reading. While at it, also make these PLLs fixed since
their rate is supposed to *never* be changed while the system runs, as
this would surely crash the entire SoC.

Now all the children of all the PLLs are also complying with their
specified clock table and system stability is improved.

clk: sunxi-ng: Add support for the Allwinner H616 CCU
While the clocks are fairly similar to the H6, many differ in tiny
details, so a separate clock driver seems indicated.

Derived from the H6 clock driver, and adjusted according to the manual.

Nicolas Pitre 0bfa0820c2 PM: clk: make PM clock layer compatible with clocks that must sleep
The clock API splits its interface into sleepable ant atomic contexts:

 - clk_prepare/clk_unprepare for stuff that might sleep

 - clk_enable_clk_disable for anything that may be done in atomic context

The code handling runtime PM for clocks only calls clk_disable() on
suspend requests, and clk_enable on resume requests. This means that
runtime PM with clock providers that only have the prepare/unprepare
methods implemented is basically useless.

Many clock implementations can't accommodate atomic contexts. This is
often the case when communication with the clock happens through another
subsystem like I2C or SCMI.

Let's make the clock PM code useful with such clocks by safely invoking
clk_prepare/clk_unprepare upon resume/suspend requests. Of course, when
such clocks are registered with the PM layer then pm_runtime_irq_safe()
can't be used, and neither pm_runtime_suspend() nor pm_runtime_resume()
may be invoked in atomic context.

For clocks that do implement the enable and disable methods then
everything just works as before.

A note on sparse:
According to https://lwn.net/Articles/109066/ there are things
that sparse can't cope with. In particular, pm_clk_op_lock() and
pm_clk_op_unlock() may or may not lock/unlock psd->lock depending on
some runtime condition. To work around that we tell it the lock is
always untaken for the purpose of static analisys.

Thanks to Naresh Kamboju for reporting issues with the initial patch.

clk: sunxi-ng: h6: Fix clock divider range on some clocks
While comparing clocks between the H6 and H616, some of the M factor
ranges were found to be wrong: the manual says they are only covering
two bits [1:0], but our code had "5" in the number-of-bits field.

By writing 0xff into that register in U-Boot and via FEL, it could be
confirmed that bits [4:2] are indeed masked off, so the manual is right.

Change to number of bits in the affected clock's description.

Liu Ying e4c0ca7894 clk: imx: clk-imx8qxp: Register DC0 display clocks with imx_clk_scu2()
This patch corrects display clocks for i.MX8qxp DC0 subsystem by
calling imx_clk_scu2() to register them, instead of calling
imx_clk_scu().  The reason is that the clocks can source from
various parents.  The clock source selection is controlled by
Distributed Slave System Controller(DSC).  According to the DSC spec,
the below table describes the generic source selections for clocks
with the same type in various subsystems.  And, the display controller
subsystem spec says the display clocks can source from PLL1, PLL2 or
bypass clock, thus we may specify the correct parents for imx_clk_scu2().

The bypass clock's parent is determined by the SCU firmware.
Currently, the parent is 'pixel_link_clk_in' from HW point of view.
To be more specific, the parent is dummy for i.MX8qxp DC0, while
HDMI TX PHY PLL for i.MX8qm DC0.  In practice, the display clocks
source from the bypass clock only when driving i.MX8qm HDMI TX.
So, for the both display clocks, we simply specify 'dc0_bypass0_clk'
bypass clock as a valid parent.

Linus Torvalds 8653b778e4 The core framework got some nice improvements this time around. We gained the
ability to get struct clk pointers from a struct clk_hw so that clk providers
 can consume the clks they provide, if they need to do something like that. This
 has been a long missing part of the clk provider API that will help us move
 away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are
 added for the clk_set_rate() "range" functions, similar to the tracepoints we
 already have for clk_set_rate() and we added a column to debugfs to help
 developers understand the hardware enable state of clks in case firmware or
 bootloader state is different than what is expected. Overall the core changes
 are mostly improving the clk driver writing experience.
 
 At the driver level, we have the usual collection of driver updates and new
 drivers for new SoCs. This time around the Qualcomm folks introduced a good
 handful of clk drivers for various parts of three or four SoCs. The SiFive
 folks added a new clk driver for their FU740 SoCs, coming in second on the
 diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that
 for various new features. One last thing to note in the driver area is that the
 i.MX driver has gained a new binding to support SCU clks after being on the
 list for many months. It uses a two cell binding which is sort of rare in clk
 DT bindings. Beyond that we have the usual set of driver fixes and tweaks that
 come from more testing and finding out that some configuration was wrong or
 that a driver could support being built as a module.
 
 Core:
  - Add some trace points for clk_set_rate() "range" functions
  - Add hardware enable information to clk_summary debugfs
  - Replace clk-provider.h with of_clk.h when possible
  - Add devm variant of clk_notifier_register()
  - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
 
 New Drivers:
  - Bindings for Canaan K210 SoC clks
  - Support for SiFive FU740 PRCI
  - Camera clks on Qualcomm SC7180 SoCs
  - GCC and RPMh clks on Qualcomm SDX55 SoCs
  - RPMh clks on Qualcomm SM8350 SoCs
  - LPASS clks on Qualcomm SM8250 SoCs

Pull clk updates from Stephen Boyd:
 "The core framework got some nice improvements this time around. We
  gained the ability to get struct clk pointers from a struct clk_hw so
  that clk providers can consume the clks they provide, if they need to
  do something like that. This has been a long missing part of the clk
  provider API that will help us move away from exposing a struct clk
  pointer in the struct clk_hw. Tracepoints are added for the
  clk_set_rate() "range" functions, similar to the tracepoints we
  already have for clk_set_rate() and we added a column to debugfs to
  help developers understand the hardware enable state of clks in case
  firmware or bootloader state is different than what is expected.
  Overall the core changes are mostly improving the clk driver writing
  experience.

  At the driver level, we have the usual collection of driver updates
  and new drivers for new SoCs. This time around the Qualcomm folks
  introduced a good handful of clk drivers for various parts of three or
  four SoCs. The SiFive folks added a new clk driver for their FU740
  SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic
  SoCs had lots of work done after that for various new features. One
  last thing to note in the driver area is that the i.MX driver has
  gained a new binding to support SCU clks after being on the list for
  many months. It uses a two cell binding which is sort of rare in clk
  DT bindings. Beyond that we have the usual set of driver fixes and
  tweaks that come from more testing and finding out that some
  configuration was wrong or that a driver could support being built as
  a module.

  Summary:

  Core:
   - Add some trace points for clk_set_rate() "range" functions
   - Add hardware enable information to clk_summary debugfs

Commit 45c940184b ("dt-bindings: clk: versaclock5: convert to

"idt,voltage-microvolt" in the DT bindings, while the driver still used
the former.

Update the driver to match the bindings, as
Documentation/devicetree/bindings/property-units.txt actually recommends
using "microvolt".

Paul Cercueil 11a163f2c7 clk: ingenic: Fix divider calculation with div tables
The previous code assumed that a higher hardware value always resulted
in a bigger divider, which is correct for the regular clocks, but is
an invalid assumption when a divider table is provided for the clock.

Perfect example of this is the PLL0_HALF clock, which applies a /2
divider with the hardware value 0, and a /1 divider otherwise.

than 200MHz and MCK0 maximum prescaller is 5 limit the CPU PLL at
1GHz to avoid MCK0 overclocking while CPU PLL is changed by DVFS.

Claudiu Beznea f803858af8 clk: at91: sama7g5: decrease lower limit for MCK0 rate
On SAMA7G5 CPU clock is changed at run-time by DVFS. Since MCK0 and
CPU clock shares the same parent clock (CPUPLL clock) the MCK0 is
also changed by DVFS to avoid over/under clocking of MCK0 consumers.
The lower limit is changed to be able to set MCK0 accordingly by
DVFS.

Claudiu Beznea 4011f03ee4 clk: at91: sama7g5: remove mck0 from parent list of other clocks
MCK0 is changed at runtime by DVFS. Due to this, since not all IPs
are glitch free aware at MCK0 changes, remove MCK0 from parent list
of other clocks (e.g. generic clock, programmable/system clock, MCKX).

Claudiu Beznea 8dc4af8bef clk: at91: clk-sam9x60-pll: allow runtime changes for pll
Allow runtime frequency changes for PLLs registered with proper flags.
This is necessary for CPU PLL on SAMA7G5 which is used by DVFS.
