Pull "The i.MX device tree updates for 4.1" from Shawn Guo:
- Convert GPC controller to use stacked interrupt domains
- Add power domain descriptions for i.MX6 platforms
- Improve i.MX25 pin function defines
- Disable PWM devices in <soc>.dtsi by default and enable it at board
level dts where the device is actually available.
- Define labels for SNVS RTC device to ease the board description,
where an external RTC is available.
- Add dr_mode host setting to all i.MX host-only USB instances
- Support Miscellaneous System Control Module (MSCM) for VF610
- Add initial i.MX6SL WaRP Board support
- Add i.MX6SX SDB revision B board support
- A bunch of imx28-apf28dev board updates, including gpio polarity
correction and CAN, AUART device support.
- SolidRun iMX6 platform updates: dual-license of GPLv2/X11, PWM
setup, PCF8523 RTC, GPIO key and SGTL5000 audio support.
- A number of random device additions for boards: SPI and CAN for
vf-colibri, MAX7310 GPIO expander for imx6qdl-sabreauto and LCD
support for imx25-pdk.
Note: Branch imx/cleanup was merged as the base to solve conflict on
imx25 iomux header. Branch imx/soc was merged as the base to solve
conflict on arch/arm/mach-imx/gpc.c. And Jason Cooper's irqchip/vybrid

Merge tag 'omap-for-v4.1/prcm-dts' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/late
Pull "Clean-up for omap PRCM (Power Reset Clock Management) and interconnects" from Tony Lindgren
Patches originally from Tero Kristo <t-kristo@ti.com>.
This sets gets us into a better position for further clean-up:
- Gets PRCM code closer to being device drivers
- Allows to move the remainig clock code to drivers/clk for v4.2
- Starts enforcing interconnect hierarchy in the SoC specific .dts
files to enforce device drivers are only accesing registers in
the related hardware module
This patchset has seen quite a few revisions but did not come into
mergeable shape until recently. As other patchsets for clock specific
device drivers depend on this, it would be good to get this merged
although it's a bit late for the v4.1 merge window.
Note that as the device entries in the .dts files are moved around,
this is based on earlier non-urgent fixes to avoid a non-trivial
merge conflict.

ARM: dts: vf610: add Miscellaneous System Control Module (MSCM)
Add the Miscellaneous System Control Module (MSCM) to the base
device tree for Vybrid SoC's. This module contains registers
to get information of the individual and current (accessing)
CPU. In a second block, there is an interrupt router, which
handles the routing of the interrupts between the two CPU cores
on VF6xx variants of the SoC. However, also on single core
variants the interrupt router needs to be configured in order
to receive interrupts on the CPU's interrupt controller. Almost
all peripheral interrupts are routed through the router, hence
the MSCM module is the default interrupt parent for this SoC.
In a earlier commit the interrupt nodes were moved out of the
peripheral nodes and specified in the CPU specific vf500.dtsi
device tree. This allowed to use the base device tree vfxxx.dtsi
also for a Cortex-M4 specific device tree, which uses different
interrupt nodes due to the NVIC interrupt controller. However,
since the interrupt parent for peripherals is the MSCM module
independently which CPU the device tree is used for, we can move
the interrupt nodes into the base device tree vfxxx.dtsi again.
Depending on which CPU this base device tree will be used with,
the correct parent interrupt controller has to be assigned to
the MSCM-IR node (GIC or NVIC). The driver takes care of the
parent interrupt controller specific needs (interrupt-cells).

There is no need to provide the CM base address through a low-level API

ARM: OMAP2+: clock: move clock provider infrastructure to clock driver
Splits the clock provider init out of the PRM driver and moves it to
clock driver. This is needed so that once the PRCM drivers are separated,
they can logically just access the clock driver not needing to go through
common PRM code. This would be wrong in the case of control module for
example.

ARM: dts: am57xx-beagle-x15: Add thermal map to include fan and tmp102
BeagleBoard-X15 has capability for a fan and has an onboard TMP102
temperature sensor as well. This allows us to create a new thermal
zone (called, un-imaginatively "board"), and allows us to use some
active cooling as temperatures start edge upward in the system by
creating a new alert temperature (emperically 50C) for cpu.
NOTE: Fan is NOT mounted by default on the platform, in such a case,
all we end up doing is switch on a regulator and leak very minimal
current.

ARM: dts: DRA7: Add bandgap and related thermal nodes
Add bandgap and related thermal nodes. The patch adds 5 thermal
sensors. Only one cooling device for mpu as of now. The sensors are
the exact same on both dra72 and dra7. Introduce CPU, GPU, core nodes
for the moment as they are direct reuse of OMAP5 entities.
NOTE: OMAP4 has a finer counter granularity, which allows for a delay
of 1000ms in the thermal zone polling intervals. DRA7 have different
counter mechanism, which allows at maximum a 500ms timer. Adjust the
cpu thermal zone accordingly for DRA7.

bus: ocp2scp: SYNC2 value should be changed to 0x6
As per the TRMs of AM572x, OMAP4430, OMAP4460, OMAP543x, the value of
SYNC2 must be set to 0x6 in order to ensure correct operation.
So modified the SYNC2 value of OCP2SCP TIMING register to 0x6 in all the
platforms that use OCP2SCP driver except AM437x. Also introduced a new
compatible property since we don't want to modify the OCP2SCP TIMING
register for AM437x.

There is a case where NULL can be a valid return value for

against a NULL pointer will fail. Thus, change the API to return a

check against IS_ERR instead.

ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688
The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a
contradiction in it's dependencies.
The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an
enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be
enabled. These options inherit a dependency from an enclosing menu,
that requires ARCH_MULTIPLATFORM to be 'enabled'.
This is a contradiction and made this option also unavailable for
non-multiplatform configurations.
Since there are no selects on OMAP4_ERRATA_I688, which would ignore
dependencies, the code related to that option is dead and can be
removed.
This (logical) defect has been found with the undertaker tool.
