Geert Uytterhoeven f3519926ba ARM: shmobile: r8a7778: Stop passing mode pins state to clock driver
Now the R-Car M1A CPG clock driver obtains the state of the mode pins
from the R-Car RST driver, there's no longer a need to pass this state
explicitly. Hence we can just remove the .init_time() callback, the
generic ARM code will take care of calling of_clk_init().

Simon Horman e11fc79521 ARM: shmobile: only call rcar_gen2_clocks_init() if present
The RZ/G1M (r8a7743) uses the R-Car Gen2 core, but not the R-Car Gen2 clock
driver. This is a harbinger of a transition for R-Car Gen2 SoCs. As the
process to get all the required pieces in place is somewhat complex it
seems useful to try to disentangle dependencies where possible.

The approach here is to temporarily disable calling rcar_gen2_clocks_init()
if no R-Car Gen2 SoC are configured and thus the symbol will not be
present.

Linus Torvalds 66f2c6d952 ARM: SoC platform updates for v4.9
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

Linus Torvalds a771151a83 ARM: SoC cleanups for v4.9
The cleanups for v4.9 are a little larger that usual, but thankfully
 that is almost exclusively due to removing a significant number of
 files that have become obsolete after the still ongoing conversion
 of old board files to devicetree.
 
 - for mach-omap2, which is still the largest platform in arch/arm/,
   the conversion to DT is finally complete after the Nokia N900 is
   now fully supported there, along with the omap3 LDP, and we can
   remove those two board files.
   If no regressions are found, another large cleanup for the platform
   will happen as a follow-up, removing dead code and restructuring
   the platform based on being DT-only.
 
 - In mach-imx, similar work is ongoing, but has not come that far.
   This time, we remove the obsolete board file for the i.MX1
   generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
   The remaining board files are for i.MX2 and i.MX3 machines
   based on old ARM926 or ARM1136 cores that should work with DT
   in principle.
 
 - realview has just been converted from board files to DT, and a lot
   of code gets removed in the process. This is the last
   ARM/Keil/Versatile derived platform that was still using board
   files, the other ones being integrator, versatile and vexpress.
   We can probably merge the remaining code into a single directory
   in the near future.
 
 - clps711x had completed the conversion in v4.8, but we accidentally
   left the files in place that should have been deleted then.
 
 Conflicts: two files deleted here have been modified upstream,
 the changes can be discarded.

Wolfram Sang c2f321126e ARM: shmobile: fix regulator quirk for Gen2
The current implementation only works if the da9xxx devices are added
before their drivers are registered. Only then it can apply the fixes to
both devices. Otherwise, the driver for the first device gets probed
before the fix for the second device can be applied. This is what
fails when using the IP core switcher or when having the i2c master
driver as a module.

So, we need to disable both da9xxx once we detected one of them. We now
use i2c_transfer with hardcoded i2c_messages and device addresses, so we
don't need the da9xxx client devices to be instantiated. Because the
fixup is used on specific boards only, the addresses are not going to
change.

Add a function to check if other DT based method is available, and
if so return false to not hook up smp_ops from the machine vector.

This results in that DT-based SMP support has priority over older
C-based smp_ops code, and in case DT-based SMP support code does not
exist in the DTB then the old smp_ops code will still work as-is.

On some R-Car Gen2 SoCs, the frequency of the ARM architecture timer
depends on the frequency of the external clock crystal.  Currently the
latter is determined indirectly from the state of the mode pins, which
is a relic predating DT.

Obtain the external clock crystal frequency from DT instead, removing
the dependency on the mode pins.

Geert Uytterhoeven 053239987f soc: renesas: rcar-sysc: Move SYSC interrupt config to rcar-sysc driver
On R-Car H1 and Gen2, the SYSC interrupt registers are always configured
using hardcoded values in platform code. For R-Car Gen2, values are
provided for H2 and M2-W only, other SoCs are not yet supported, and
never will be.

Move this configuration from SoC-specific platform code to the
rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured
from DT. This would be the case not only for H1, H2, and M2-W using a
modern DTS, but also for other R-Car Gen2 SoCs not supported by the
platform code, relying purely on DT.

There is no longer a need to return the mapped register block, hence
make the function return void.

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

  - R-Car M2-N uses Inter Connect RAM in Magnus Damm's "ARM: shmobile:

 controllers, which have not yet been abstracted into a separate

 Another large chunk here is a rework of the NVIDIA Tegra USB3.0

Linus Torvalds 9896c7b57e ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount
 of changes in arch/arm for any of them is miniscule, as all the
 interesting code is in device driver subsystems (irqchip, clk, pinctrl,
 ...) these days. I'm listing them here, as the addition of the Kconfig
 statement is the main relevant milestone for a new platform. In each
 case, some drivers are are shared with existing platforms, while
 other drivers are added for v4.7 as well, or come in a later release.
 
 - The Aspeed platform is probably the most interesting one, this is
   what most whitebox servers use as their baseboard management
   controller. We get support for the very common ast2400 and ast2500
   SoCs. The OpenBMC project focuses on this chip, and the LWN
   article about their ELC 2016 presentation at
   https://lwn.net/Articles/683320/ triggered the submission, but the
   code comes from IBM's OpenPOWER team rather than the team at
   Facebook. There are still a lot more drivers that need to get added
   over time, and I hope both teams can work together on that.
 
 - OXNAS is an old platform for Network Attached Storage devices
   from Oxford Semiconductor. There are models with ARM10 (!) and
   ARM11MPCore cores, but for now, we only support the original ARM9
   based versions.
   The product lineup was subsequently part of PLX, Avago and now the
   new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
   has some more information.
 
 - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
   cores and is related to the existing Realview / Versatile Express
   lineup, but without MMU. We now support various NOMMU platforms,
   so adding a new one is fairly straightforward.
   http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
   has detailed information about the platform.
 
 Other noteworthy updates:
 
 - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux
   are now maintaining the platform. This is an older ARM9 based
   platform from NXP (not Freescale), but it remains in use in embedded
   markets.
 
 - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both
   32-bit and 64-bit ARM, and started contributing some patches.
 
 - As is often the case, work on the OMAP platforms makes up the bulk of
   the actual SoC code changes in arch/arm, but there isn't a lot of
   that either.

Geert Uytterhoeven be32bcbbd1 soc: renesas: Move pm-rcar to drivers/soc/renesas/rcar-sysc
Move the pm-rcar driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and its header file to include/linux/soc/renesas/,
so it can be shared between arm32 (R-Car H1 and Gen2) and arm64 (R-Car
Gen3). Rename it to rcar-sysc as it's really a driver for the R-Car
System Controller (SYSC).

Kill the intermediate PM_RCAR config symbol, as it's not user
configurable anymore, and to prepare for SoC-specific make rules.

Add the missing #include <linux/types.h> to rcar-sysc.h, which was
exposed by different include order.

Geert Uytterhoeven a4b8c18c40 ARM: shmobile: timer: Drop support for Cortex A8
Commit edf4100906 ("ARM: shmobile: sh7372 dtsi: Remove Legacy
file") removed the DTS for the last shmobile SoC with a Cortex A8 CPU
core (sh7372 aka SH-Mobile AP4), hence drop support for it in the
loops-per-jiffy preset code.

As "div" is always 1 for supported contemporary ARM processors, we can
simplify the code:
  - Absorb shmobile_setup_delay_hz(), which was always called with
    mult = div = 1,
  - Return earlier if the Cortex A7/A15 arch timer exists and support is
    enabled.

Geert Uytterhoeven c531fb27e9 ARM: shmobile: timer: Fix preset_lpj leading to too short delays
On all shmobile ARM SoCs, loop-based delays may complete early, which
can be after only 1/3 (Cortex A9) or 1/2 (Cortex A7 or A15) of the
minimum required time.

This is caused by calculating preset_lpj based on incorrect assumptions
about the number of clock cycles per loop:
  - All of Cortex A7, A9, and A15 run __loop_delay() at 1 loop per
    CPU clock cycle,
  - As of commit 11d4bb1bd0 ("ARM: 7907/1: lib: delay-loop: Add
    align directive to fix BogoMIPS calculation"), Cortex A8 runs
    __loop_delay() at 1 loop per 2 instead of 3 CPU clock cycles.

On SoCs with Cortex A7 and/or A15 CPU cores, this went unnoticed, as
delays use the ARM arch timer if available. R-Car Gen2 doesn't work if
the arch timer is disabled. However, APE6 can be used without the arch
timer.

This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

Along with the above mentioned Kconfig changes it seems appropriate
to also rename files.

Geert Uytterhoeven 71d076ceb2 ARM: shmobile: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM Domains
All supported Renesas ARM SoCs (except for Emma Mobile EV2) have clock
domains. Some SoCs also have power domains. To ensure proper operation
of on-SoC modules, module clocks must be ungated, and power domains must
be powered up when needed.

Currently the user can choose to build a kernel with power management
enabled or disabled:
  - If CONFIG_PM=y, power domains and/or module clocks are handled
    dynamically by Runtime PM and the generic power domain.
  - If CONFIG_PM=n, power domains are assumed to be powered up by reset
    state or by the boot loader, and module clocks are handled by the
    legacy clock domain on driver (un)bind.
    The latter is implemented using a platform bus notifier, which
    applies not only to all on-SoC devices, but to all platform devices
    present in the system.

To remove the dependency on implicit assumptions, and to get rid of the
peculiarities of the legacy clock domain, enable CONFIG_PM and
CONFIG_PM_GENERIC_DOMAINS unconditionally, for all Renesas ARM SoCs with
clock and/or power domains.

This does cause an increase in kernel size.  Given bloat-o-meter reports
a modest increase of 26 KiB for an RZ/A1H kernel, this should not be a
problem, even when used on RZ/A1H with XIP and internal RAM only.

Geert Uytterhoeven 8701d8083d ARM: shmobile: Consolidate SCU mapping code
Currently the SCU registers are mapped in SoC-specific code, using
different methods, all involving the static mapping set up from
machine_desc.map_io():
  - On emev2, a static (non-identity) mapping is used, with ioremap().
    As the static mapping uses the MT_DEVICE type, ioremap() reuses it,
    and the returned virtual address is suitable for passing to
    shmobile_smp_hook(),
  - On sh73a0 and r8a7779, a static identity mapping is used, with the
    legacy IOMEM() macro.
    As the static mapping uses the MT_DEVICE_NONSHARED type, replacing
    IOMEM() by ioremap() would create a new mapping, whose virtual
    address cannot be passed to shmobile_smp_hook().

Move the mapping of the SCU registers from SoC-specific code to common
code, always using ioremap(). To work in the absence of a static
mapping, this requires passing the physical SCU base address to
shmobile_smp_hook().

Geert Uytterhoeven 901c5ffaae ARM: shmobile: Remove shmobile_boot_arg
CPU boot configuration writes to shmobile_boot_arg, which is located in
the .text section, and thus should not be written to.

As of commit 1d33a354bb ("ARM: shmobile: Per-CPU SMP boot / sleep
code for SCU SoCs"), and ignoring accidental remainings,
shmobile_boot_arg is always set to MPIDR_HWID_BITMASK by C code.
Hence we can just hardcode this in the assembler code, and remove the
variable, and thus also remove the need to write to this variable.

This happens because the .text section is marked read-only, while the
arrays shmobile_smp_mpidr[], shmobile_smp_fn[], and shmobile_smp_arg[]
are being written to.

Fix this by moving these arrays from the .text to the .bss section.
This requires accessing them through PC-relative offsets.

Masahiro Yamada e324654294 ARM: use "depends on" for SoC configs instead of "if" after prompt
Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.

Please notice the difference between

    config ARCH_FOO
            bool "Foo SoCs" if ARCH_MULTI_V7

and

    config ARCH_FOO
            bool "Foo SoCs"
            depends on ARCH_MULTI_V7

These two are *not* equivalent!

In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7.  So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns.  This is probably not what
you want.

The former should be used only when you need to do so, and you really
understand what you are doing.  (In most cases, it should be wrong!)

For enabling/disabling sub-architectures, the latter is always correct.

As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).

[Arnd: I note that there is not really a bug here, according to
 the discussion that followed, but I can see value in being consistent
 and in making the lines shorter]

Linus Torvalds a5e1d715a8 ARM: SoC cleanups for v4.4
Again we have a sizable (but not huge) cleanup branch with a net delta of about
 -3k lines.
 
 Main contents here is:
 
  - A bunch of development/cleanup of a few PXA boards
  - Removal of bockw platforms on shmobile, since the platform has now gone
    completely multiplatform. Whee!
  - move of the 32kHz timer on OMAP to a proper timesource
  - Misc cleanup of older OMAP material (incl removal of one board file)
  - Switch over to new common PWM lookup support for several platforms
 
 There's also a handful of other cleanups across the tree, but the above are
 the major pieces.

Geert Uytterhoeven 8b98d74780 ARM: shmobile: R-Mobile: Use CPG/MSTP Clock Domain attach/detach helpers
The R-Mobile PM Domain driver manages both power domains and a clock
domain.

The clock domain part is very similar to the CPG/MSTP Clock Domain,
which is used on shmobile SoCs without device power domains, except for
the way how clocks suitable for power management are selected:
  - The former uses the first clock tied to the device through the NULL
    con_id, which is a relic from the legacy pm_clk_notifier-based
    method in drivers/sh/pm_runtime.c,
  - The latter looks for suitable clocks in DT, which is more
    future-proof.

All platforms using this driver are now supported in DT-based ARM
multi-platform builds only, hence switch to using the CPG/MSTP Clock
Domain helpers.

Linus Torvalds c706c7eb0d Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM development updates from Russell King:
 "Included in this update:

   - moving PSCI code from ARM64/ARM to drivers/

   - removal of some architecture internals from global kernel view

   - addition of software based "privileged no access" support using the
     old domains register to turn off the ability for kernel
     loads/stores to access userspace.  Only the proper accessors will
     be usable.

   - addition of early fixup support for early console

   - re-addition (and reimplementation) of OMAP special interconnect
     barrier

   - removal of finish_arch_switch()

   - only expose cpuX/online in sysfs if hotpluggable

   - a number of code cleanups"

Linus Torvalds 102178108e ARM: SoC driver updates for v4.3
Some releases this branch is nearly empty, others we have more stuff. It
 tends to gather drivers that need SoC modification or dependencies such
 that they have to (also) go in through our tree.
 
 For this release, we have merged in part of the reset controller tree
 (with handshake that the parts we have merged in will remain stable),
 as well as dependencies on a few clock branches.
 
 In general, new items here are:
 
 - Qualcomm driver for SMM/SMD, which is how they communicate with the
   coprocessors on (some) of their platforms
 - Memory controller work for ARM's PL172 memory controller
 - Reset drivers for various platforms
 - PMU power domain support for Marvell platforms
 - Tegra support for T132/T210 SoCs: PMC, fuse, memory controller per-SoC support

Stephen Boyd 787047eea2 ARM: 8392/3: smp: Only expose /sys/.../cpuX/online if hotpluggable
Writes to /sys/.../cpuX/online fail if we determine the platform
doesn't support hotplug for that CPU. Furthermore, if the cpu_die
op isn't specified the system hangs when we try to offline a CPU
and it comes right back online unexpectedly. Let's figure this
stuff out before we make the sysfs nodes so that the online file
doesn't even exist if it isn't (at least sometimes) possible to
hotplug the CPU.

Add a new 'cpu_can_disable' op and repoint all 'cpu_disable'
implementations at it because all implementers use the op to
indicate if a CPU can be hotplugged or not in a static fashion.
With PSCI we may need to add a 'cpu_disable' op so that the
secure OS can be migrated off the CPU we're trying to hotplug.
In this case, the 'cpu_can_disable' op will indicate that all
CPUs are hotpluggable by returning true, but the 'cpu_disable' op
will make a PSCI migration call and occasionally fail, denying
the hotplug of a CPU. This shouldn't be any worse than x86 where
we may indicate that all CPUs are hotpluggable but occasionally
we can't offline a CPU due to check_irq_vectors_for_cpu_disable()
failing to find a CPU to move vectors to.

Sudeep Holla 0d3f2c92e0 irqchip/gic: Remove redundant gic_set_irqchip_flags
Now that the GIC chip implementation enables IRQCHIP_SKIP_SET_WAKE and
IRQCHIP_MASK_ON_SUSPEND by default, the platforms requiring them need
not override the irqchip flags as before.

This patch removes all the users of gic_set_irqchip_flags and the
function itself.

Simplify the power request code by passing an "on" flag, and picking the
right status bit and register offset in the innermost function, based on
this flag.
This allows to remove the rcar_sysc_pwr_{off,on}() helper functions, and
the function pointer through which they were called.

Make sr_bit and reg_offs unsigned while we're at it.

rcar_sysc_update() loops (with interrupts disabled and while holding a
spinlock) until submitting a power shutoff or resume request fails, or
until the submitted request was accepted.
If none of these conditions becomes true, this forms an infinite loop.

Shrink the individual fields in struct rcar_sysc_ch, as unsigned long or
int is overkill:
  - chan_offs contains a register offset relative to a base value
    (< 512),
  - chan_bit and isr_bit contain bit indices (0-31).

This reduces the size of each instance from 3 (4 on 64-bit) 32-bit words
to 1 32-bit word.

The R-Car SYSC PM Domain only manages power domains for the main CPUs
and for coprocessors. It does not fill in the genpd .{at,de}tach_dev()
callbacks, and no power management clocks are registered for devices.
Hence pm_clk_{suspend,resume}() are no-ops, and setting of the
GENPD_FLAG_PM_CLK flag can be removed.

Originally the clock handling was copied from the R-Mobile PM Domain
code, which does manage a clock domain, in addition to device power
domains.

Russell King 02b4e2756e ARM: v7 setup function should invalidate L1 cache
All ARMv5 and older CPUs invalidate their caches in the early assembly
setup function, prior to enabling the MMU.  This is because the L1
cache should not contain any data relevant to the execution of the
kernel at this point; all data should have been flushed out to memory.

This requirement should also be true for ARMv6 and ARMv7 CPUs - indeed,
these typically do not search their caches when caching is disabled (as
it needs to be when the MMU is disabled) so this change should be safe.

ARMv7 allows there to be CPUs which search their caches while caching is
disabled, and it's permitted that the cache is uninitialised at boot;
for these, the architecture reference manual requires that an
implementation specific code sequence is used immediately after reset
to ensure that the cache is placed into a sane state.  Such
functionality is definitely outside the remit of the Linux kernel, and
must be done by the SoC's firmware before _any_ CPU gets to the Linux
kernel.

Changing the data cache clean+invalidate to a mere invalidate allows us
to get rid of a lot of platform specific hacks around this issue for
their secondary CPU bringup paths - some of which were buggy.

Linus Torvalds e5ac320de1 ARM: SoC multiplatform code changes for v4.1
The changes here belong to two main platforms:
 
 - Atmel At91 is flipping the bit and going multiplatform. This includes some
   cleanups and removal of code, and the final flip of config dependencies
 
 - Shmobile has several platforms that are going multiplatform, but this
   branch also contains a bunch of cleanups that they weren't able to keep
   separate in a good way. THere's also a removal of one of their SoCs and the
   corresponding boards (sh7372 and mackerel).

 - More graphics DT pieces falling into place on Exynos, bridges, clocks.
 - Plenty of DT updates for Qualcomm platforms for various IP blocks
 - Some churn on Tegra due to switch-over to tool-generated pinctrl data
 - Misc fixes and updates for Atmel at91 platforms
 - Various DT updates to add IP block support on Broadcom's Cygnus platforms
 - More updates for Renesas platforms as DT support is added for various IP

Linus Torvalds d0a3997c0c sound updates for 4.1-rc1
There have been major modernization with the standard bus: in ALSA
 sequencer core and HD-audio.  Also, HD-audio receives the regmap
 support replacing the in-house cache register cache code.  These
 changes shouldn't impact the existing behavior, but rather
 refactoring.
 
 In addition, HD-audio got the code split to a core library part and
 the "legacy" driver parts.  This is a preliminary work for adapting
 the upcoming ASoC HD-audio driver, and the whole transition is still
 work in progress, likely finished in 4.1.
 
 Along with them, there are many updates in ASoC area as usual, too:
 lots of cleanups, Intel code shuffling, etc.
 
 Here are some highlights:
 
 ALSA core:
 - PCM: the audio timestamp / wallclock enhancement
 - PCM: fixes in DPCM management
 - Fixes / cleanups of user-space control element management
 - Sequencer: modernization using the standard bus
 
 HD-audio:
 - Modernization using the standard bus
 - Regmap support
 - Use standard runtime PM for codec power saving
 - Widget-path based power-saving for IDT, VIA and Realtek codecs
 - Reorganized sysfs entries for each codec object
 - More Dell headset support

Merge tag 'sound-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There have been major modernization with the standard bus: in ALSA
  sequencer core and HD-audio.  Also, HD-audio receives the regmap
  support replacing the in-house cache register cache code.  These
  changes shouldn't impact the existing behavior, but rather
  refactoring.

  In addition, HD-audio got the code split to a core library part and
  the "legacy" driver parts.  This is a preliminary work for adapting
  the upcoming ASoC HD-audio driver, and the whole transition is still
  work in progress, likely finished in 4.1.

  Along with them, there are many updates in ASoC area as usual, too:
  lots of cleanups, Intel code shuffling, etc.

  Here are some highlights:

  ALSA core:
   - PCM: the audio timestamp / wallclock enhancement
   - PCM: fixes in DPCM management
   - Fixes / cleanups of user-space control element management
   - Sequencer: modernization using the standard bus

  HD-audio:
   - Modernization using the standard bus
   - Regmap support
   - Use standard runtime PM for codec power saving
   - Widget-path based power-saving for IDT, VIA and Realtek codecs
   - Reorganized sysfs entries for each codec object
   - More Dell headset support

  ASoC:
   - Move of jack registration to the card level
   - Lots of ASoC cleanups, mainly moving things from the CODEC level to
     the card level
   - Support for DAPM routes specified by both the machine driver and DT
   - Continuing improvements to rcar
   - pcm512x enhacements
   - Intel platforms updates
   - rt5670 updates / fixes
   - New platforms / devices: some non-DSP Qualcomm platforms, Google's
     Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC
