Pull ARM SoC fixes from Olof Johansson:
"A smallish batch of fixes, a little more than expected this late, but
all fixes are contained to their platforms and seem reasonably low
risk:
- a somewhat large SMP fix for ux500 that still seemed warranted to
include here
- OMAP DT fixes for pbias regulator specification that broke due to
some DT reshuffling
- PCIe IRQ routing bugfix for i.MX
- networking fixes for keystone
- runtime PM for OMAP GPMC
- a couple of error path bug fixes for exynos"

Currently mdio bindings are defined in keystone.dtsi and this results
in incorrect unit address for the node on K2E and K2L SoCs. Fix this
by moving them to SoC specific DTS file.

Few trivial omap MMC regression fixes for card voltages where

This probably was not noticed earlier as the bootloader has

The PCIe interrupts are also routed through the GPC. This has been
missed from the conversion to stacked IRQ domains as the PCIe
controller uses an explicit interrupt map and thus doesn't inherit
the SoC global interrupt parent.

The "cpus" node cannot be inside the "soc" node, while this
works for the CoreSight blocks, the early boot code will look
for "cpus" directly under the root node, so this is a hard
convention. So move the CPU nodes.
Augment the "reg" property to match what is actually in the
hardware: 0x300 and 0x301 respectively.
Then add an SMP enablement type to be used by the SMP init
code, "ste,dbx500-smp".

Currently PCIe DT bindings are broken. PCIe driver can't function
without having a SerDes driver that provide the phy configuration.
On K2E EVM, this causes problem since the EVM has Marvell SATA
controller present and with default values in the SerDes register,
it seems to pass the PCIe link check, but causes issues since
the configuration is not correct. The manifestation is that when
EVM is booted with NFS rootfs, the boot hangs. We shouldn't enable
PCIe on this EVM since to work, SerDes driver has to be present as
well. So by default, the PCIe DT binding should be disabled in SoC
specific DTS. It can be enabled in the board specific DTS when the
SerDes device driver is also present.
So fix the status of PCIe DT bindings in the SoC specific DTS to
"disabled". To enable PCIe, the status should be set to "ok" in
the EVM DTS file when SerDes driver support becomes available in
the upstream tree.

Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There
is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works.

Ux500 is regressing due to commit
a21763a0b1e5a5ab8310f581886d04beadc16616
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.
The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).
The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.
To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

for OMAP4 platforms. This property is required as per the generic
iommu binding.

The device tree for Gumstix Pepper has DCDC2 and
DCDC3 correctly labelled but the upper limit values
are wrong. The confusion is due to the hardware
quirk where the DCDC2 and DCDC3 wires are flipped
in Pepper.

Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.
Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.
The consumers of the regulators this commit affect are the followings:
DCDC1: vdd_1v8 system supply, USB-PHY, and ADC
DCDC2: Core domain
DCDC3: MPU core domain
LDO1: RTC
LDO2: 3v3 IO domain
LDO3: USB-PHY; not a boot-time requirement
LDO4: LCD [16:23]
All but LDO3 need to be always-on for the system to be functional.
Additionally regulator-name properties have been added for the kernel to
display the name from the schematic. This will improve diagnostics.

For Gumstix Overo COMs, the u-boot bootloader typically passes an
argument specifying the default display via the omapdss.def_disp
parameter. When a default display is specified, DSS2 tries to match
this name with either the device tree label (e.g. label=dvi) or,
failing this, the device tree alias (e.g. label=display0). Update the
panel names for the 'lcd43' and 'lcd35' displays in the device tree
such that they match the names passed by u-boot.

Driver core sets "default" pinmux on on probe and CAN driver
sets "sleep" pinmux during register. This causes a small window
where the CAN pins are in "default" state with the DCAN module
being disabled.
Change the "default" state to be like sleep so this glitch is
avoided. Add a new "active" state that is used by the driver
when CAN is actually active.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Merge "omap fixes against v4.2-rc1" from Tony Lindgren:
Minor fixes for omaps against v4.2-rc1. Mostly just minor dts changes
except for a GPMC fix to not use names for probing devices. Also a
one liner clean-up to remove unecessary return from a void function.
The summary for the changes being:
- Fix probe for GPMC devices by reoving limitations based on device
name
- Remove unnecessary return from a void function
- Revert beaglebone RTC sleep fix, we now have a better fix merged
- Add am4372 EMIF node to fix a warning
- Add am57xx-beagle-x15 power supply to fix USB2 if USB1 is disabled
- Disable rfbi for am4372 as it does not have a driver
* tag 'omap-for-v4.2/fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: dts: am4372.dtsi: disable rfbi

The CCI device node was added to vexpress CA15_A7(i.e. TC2) much before
the CCI PMU support and binding was added. This patch adds the missing
PMU node so that CCI PMUs can be used on TC2.

The dts for the CoreTile Express A15x2 A7x3 (TC2) only describes the
PMUs of the Cortex-A15 CPUs, and not the Cortex-A7 CPUs.
Now that we have a mechanism for describing disparate PMUs and their
interrupts in device tree, this patch makes use of these to describe the
PMUs for all CPUs in the system. For consistency, the existing A15 PMU
interrupt-affinity property is reflowed across two lines.
