of all peripherals which are GPIO line consumers for all legacy boards
from .init_machine to .init_late init level. This is needed to
proactively prevent boot time issues on the legacy boards due to the
deprioritized init level of the GPIO controller driver (set lower than
IOMUX controller driver init level), which is shared among all i.MX

This was done to make UART1-3 on H3 consistent, and less complicated to
enable UART1-3 on the breakout header on the several H3 board (notably
Orange Pi's). This patch adds a bit of complexity for the existing Banana

The RTS/CTS for UART2-3 could be defined in the same way, but since
there is no actual use case for them at the moment, they are left out.

Since the commit bd3677ff31 ("clk: mvebu: Remove corediv clock from
Armada XP"), the corediv clk is no more selected for Armada XP, however
this clock is used for Armada XP using the compatible
armada-370-corediv-clock.
While since commit 1594d568c6 ("clk: mvebu: Move corediv config to
mvebu config") Armada 38x and Armada 375 got corediv support again, not
only Armada XP was missed but also Armada 39x.
Actually all the SoC selecting MVEBU_V7 config need this clock:
git grep "\-corediv-clock" arch/arm/boot/dts
arch/arm/boot/dts/armada-370-xp.dtsi: compatible = "marvell,armada-370-corediv-clock";
arch/arm/boot/dts/armada-375.dtsi: compatible = "marvell,armada-375-corediv-clock";

arch/arm/boot/dts/armada-39x.dtsi: compatible = "marvell,armada-390-corediv-clock"
This commit now fixes this behavior by letting MVEBU_V7 select
MVEBU_CLK_COREDIV.

Pull "Topic branch for Samsung DeviceTree cleanup for 4.9" from Krzysztof Kozłowski:
Replace in DT sources hard-coded values for pinctrl configuration like pull
up/down, drive strength and function. This makes the DTS easier to read,
especially that some drive strengths values are quite non-obvious.

Here are a couple of bugfixes for v4.8-rc. Most of them have
actually been around for a while this time but for some reason
didn't get applied early on. The shmobile regulator fix is the
only one that isn't completely obvious.
device tree changes:
- archtimer interrupts must be level triggered (multiple platforms)
- fix for USB and MMC clocks on STiH410
- fix split DT repository in case of raspberry-pi 3
- A new use of skeleton.dtsi on arm64 has crept in after that
was removed.
defconfig updates:
- xilinx vdma has a new Kconfig symbol name
- keystone requires CONFIG_NOP_USB_XCEIV since v4.8-rc1
code fixes:
- fix regulator quirk on shmobile
- suspend-to-ram regression on EXYNOS
maintainer updates:
- Javier Martinez Canillas is now a reviewer for Samsung EXYNOS

Most of them have actually been around for a while this time but for
some reason didn't get applied early on. The shmobile regulator fix
is the only one that isn't completely obvious.
Device tree changes:
- archtimer interrupts must be level triggered (multiple platforms)
- fix for USB and MMC clocks on STiH410
- fix split DT repository in case of raspberry-pi 3
- a new use of skeleton.dtsi on arm64 has crept in after that was
removed.
defconfig updates:
- xilinx vdma has a new Kconfig symbol name
- keystone requires CONFIG_NOP_USB_XCEIV since v4.8-rc1
Code fixes:
- fix regulator quirk on shmobile
- suspend-to-ram regression on EXYNOS
Maintainer updates:
- Javier Martinez Canillas is now a reviewer for Samsung EXYNOS"

Pull ARM fixes from Russell King:
"Most of this update are fixes primarily discovered from testing on the
older StrongARM 1110 and PXA systems, as a result of recent interest
from several people in these platforms:
- Locomo interrupt handling incorrectly stores the handler data in
the chip's private data slot: when Locomo is combined with an
interrupt controller who's chip uses the chip private data, this
leads to an oops.
- SA1111 was missing a call to clk_disable() to clean up after a
failed probe.
- SA1111 and PCMCIA suspend/resume was broken:
The PCMCIA "ds" layer was using the legacy bus suspend/resume
methods, which the core PM code is no longer calling as a result of
device_pm_check_callbacks() introduced in commit aa8e54b559
("PM / sleep: Go direct_complete if driver has no callbacks").
SA1111 was broken due to changes to PCMCIA which makes PCMCIA
suspend itself later than the SA1111 code expects, and resume
before the SA1111 code has initialised access to the pcmcia
sub-device.
- the default SA1111 interrupt mask polarity got messed up when it
was converted to use a dynamic interrupt base number for its
interrupts.
- fix platform_get_irq() error code propagation, which was causing
problems on platforms where the interrupt may not be available at
probe time in DT setups.
- fix the lack of clock to PCMCIA code on PXA platforms, which was
omitted in conversions of PXA to CCF.
- fix an oops in the PXA PCMCIA code caused by a previous commit not
realising that Lubbock is different from the rest of the PXA PCMCIA
drivers.
- ensure that SA1111 low-level PCMCIA drivers propagate their error
codes to the main probe function, rather than the driver silently
accepting a failure.
- fix the sa11xx debugfs reporting of timing information, which
always indicated zero due to the clock being a factor of 1000 out.
- fix the polarity of the status change signal reported from the
sockets.
Lastly, one ARM specific commit from Stefan Agner fixing the LPAE
cache attributes"

broke Suspend to RAM on Exynos boards due to lack of probing of

The pinctrl drive strength register on exynos4415 is 2-bit wide for each
pin. The pins for SD2 were configured with value of 4. The driver does
not validate the value so this overflow effectively set a bit 1 in
adjacent pins thus configuring them to drive strength 2x.
The author's intention was probably to set drive strength of 4x.
All other SD pins are configured with drive strength of 4x. Fix these
with same pattern.

basically replaced mmc2_pinctrl_default with mmc1_pinctrl_default. And
kernel dutifully reports conflict of usage.
[...]

omap_hsmmc 480b4000.mmc: Error applying setting, reverse things back
omap_hsmmc 480b4000.mmc: could not initialize pin control state
[...]
But, thanks to the fact that we were in fact setting all the muxes in
U-Boot, all the MMC devices were still properly detected.
Fix the typo.

This helps to get 100% intensity closer to "always on".
It compensates for an effect of dmtimer which at 100% still emits short
"off" impulses and the startup-time of the DC/DC converter makes
backlight intensity not reach full scale. The lower the PWM frequency
is, the smaller is this effect.

rd88f6183ap-ge passes NO_IRQ as the interrupt line for its m25p80
NOR flash. However, this device never uses an interrupt and the
driver doesn't care, so we can simply remove the deprecated constant
here.

One of the last users of NO_IRQ on ARM is the switch initialization
code on orion5x, which sometimes passes a GPIO based IRQ number.
However, the driver doesn't actually use this number, and according
to Andrew Lunn never will do it for non-DT based machines, so
we can simply drop the irq argument.
Simplifying it further, we can also drop the static platform_device
and instead call platform_device_register_data(), which in turn
lets us mark the platform_data structures as __initdata and slightly
reduce the memory consumption.

For most devices, we know in advance whether they have an
interrupt line or not, so we can avoid passing NO_IRQ and
instead split fill_resources() into two interfaces, with
only the new fill_resources_irq() function taking an irq
argument, which it then can use unconditionally.

Out of the four ethernet devices on mv78xx0, only the first one
has an error interrupt line, for the other ones we pass NO_IRQ
and then ignore the argument.
In order to get closer to complete remove of NO_IRQ, this simply
drops the unused function arguments.

Commit 88e957d6e4 ("xen: introduce xen_vcpu_id mapping") broke SMP
ARM guests on Xen. When FIFO-based event channels are in use (this is
the default), evtchn_fifo_alloc_control_block() is called on
CPU_UP_PREPARE event and this happens before we set up xen_vcpu_id
mapping in xen_starting_cpu. Temporary fix the issue by setting direct
Linux CPU id <-> Xen vCPU id mapping for all possible CPUs at boot. We
don't currently support kexec/kdump on Xen/ARM so these ids always
match.
In future, we have several ways to solve the issue, e.g.:
- Eliminate all hypercalls from CPU_UP_PREPARE, do them from the
starting CPU. This can probably be done for both x86 and ARM and, if
done, will allow us to get Xen's idea of vCPU id from CPUID/MPIDR on
the starting CPU directly, no messing with ACPI/device tree
required.
- Save vCPU id information from ACPI/device tree on ARM and use it to
initialize xen_vcpu_id mapping. This is the same trick we currently
do on x86.

Some omap5 variants have more than 2GB of memory available as
optional models. Let's update the dts files to use two address
cells similar to what dra7 is using with commit dae320ec31
("ARM: dts: DRA7: change address-cells and size-cells").

Latest update to the BeagleBoard-X15 platform (revision B1)[1] updates
for allowing UHS SD cards to function with the split of supply to SD
card from a dedicated LDO.
As a result of this, AM57xx BeagleBoard-X15 now uses gpio2_30 instead
of gpio6_28 for HDMI because HDMI_LS_OE should now be switched from
GPIO6_28(Y9) to GPIO2_30 (AG8) to avoid a 1.8V GPIO toggling a 3.3V
SoC input when the SD card is in UHS 1.8V mode.
NOTE: For UHS mode to function, we need full fledged IODelay support
in kernel to be functional. IODelay support is yet to be added.
Further, It does not make much sense to spin off a new board
compatible flag since there is no real functional benefit for the
same.
Note: Even though production version is supposed to be B1, there is
over ~200 boards of previous version (A2)[2] out there which continue
to get supported with the existing dts file (to maintain compatibility
with existing bootloaders for A2) and the production board is now
supported as revb1.

Pinmuxing for DRA7x/AM57x family of processors need to be done in IO
isolation as part of initial bootloader executed from SRAM. This is
done as part of iodelay configuration sequence and is required due
to the limitations introduced by erratum ID: i869[1] (IO Glitches
can occur when changing IO settings) and elaborated in the Technical
Reference Manual[2] 18.4.6.1.7 Isolation Requirements.
Only peripheral that is permitted for dynamic pin mux configuration
is MMC and DCAN. MMC is permitted to change to accommodate the
requirements for varied speeds (which require IO-delay support in
kernel as well). DCAN is a result of i893[1] (DCAN initialization
sequence). However, since we don't use DCAN on X15, with the exception
of MMC, all other pin mux configurations are removed from the dts.

The ID pin GPIO comes from the PMIC. Let's configure it as a GPIO
for the driver to use, and also make sure the PMIC GPIO pin muxing
is correct. The PMIC pad1 and 2 values for omap5-uevm and igepv5 are
0x5a and 0x1b, we only need to clear bit 2 in pad1 register to make
the ID pin GPIO work.
