only a single reset for all DU channels.

"#address-cells", "#size-cells", and "ranges" are required properties

"make dtbs_check" emits warnings like:

To improve human readability and enable automatic validation, the tuples
in the various properties containing interrupt specifiers should be

"interrupts" property, it does for the "interrupt-map" property, leading
to warnings like:

Add properties to describe the reset topology for on-SoC devices:
- Add the "#reset-cells" property to the CPG/MSSR device node,
- Add resets and reset-names properties to the various device nodes.
This allows to reset SoC devices using the Reset Controller API.
Note that resets usually match the corresponding module clocks.
Exceptions are:
- The audio module has resets for the Serial Sound Interfaces only,
- The display module has only a single reset for all DU channels, but
adding reset properties for the display is postponed.

Link the ARM GIC to the INTC-SYS module clock, and add it to the "always
on" PM Domain, so it can be power managed using that clock.
Note that currently the GIC-400 driver doesn't support module clocks nor
Runtime PM, so this must be handled as a critical clock.

The Cortex-A7 cache controller is an integrated controller, and thus the
device node representing it should not have a unit-addresses or reg
property.

Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.
Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).
In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

Use recently added R-Car Gen 2 fallback binding for iic nodes in
DT for r8a7794 SoC.
This has no run-time effect for the current driver as the initialisation
sequence is the same for the SoC-specific binding for r8a7794 and the
fallback binding for R-Car Gen 2.

A fallback binding for the Renesas R-Car Gen2 PHY driver was

This patch makes use of this binding in the DT for the r8a7794 SoC.

Lots of changes as usual, so I'm trying to be brief here. Most of the
new hardware support has the respective driver changes merged through
other trees or has had it available for a while, so this is where things
come together.
We get a DT descriptions for a couple of new SoCs, all of them variants
of other chips we already support, and usually coming with a new
evaluation board:
- Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
- Qualcomm MDM9615 LTE baseband
- NXP imx6ull, the latest and smallest i.MX6 application processor variant
- Renesas RZ/G (r8a7743 and r8a7745) application processors
- Rockchip PX3, a variant of the rk3188 chip used in Android tablets
- Rockchip rk1108 single-core application processor
- ST stm32f746 Cortex-M7 based microcontroller
- TI DRA71x automotive processors
These are commercially available consumer platforms we now support:
- Motorola Droid 4 (xt894) mobile phone
- Rikomagic MK808 Android TV stick based on Rockchips rx3066
- Cloud Engines PogoPlug v3 based on OX820
- Various Broadcom based wireless devices:
- Netgear R8500 router
- Tenda AC9 router
- TP-LINK Archer C9 V1
- Luxul XAP-1510 Access point
- Turris Omnia open hardware router based on Armada 385
And a couple of new boards targeted at developers, makers
or industrial integration:
- Macnica Sodia development platform for Altera socfpga (Cyclone V)
- MicroZed board based on Xilinx Zynq FPGA platforms
- TOPEET itop/elite based on exynos4412
- WP8548 MangOH Open Hardware platform for IOT, based on
Qualcomm MDM9615
- NextThing CHIP Pro gadget
- NanoPi M1 development board
- AM571x-IDK industrial board based on TI AM5718
- i.MX6SX UDOO Neo
- Boundary Devices Nitrogen6_SOM2 (i.MX6)
- Engicam i.CoreM6
- Grinn i.MX6UL liteSOM/liteBoard
- Toradex Colibri iMX6 module
Other changes:
- added peripherals on renesas, davinci, stm32f429, uniphier, sti,
mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
mvebu, allwinner, broadcom, exynos, zynq
- Continued fixes for W=1 dtc warnings
- The old STiH415/416 SoC support gets removed, these never made it into
products and have served their purpose in the kernel as a template
for teh newer chips from ST
- The exynos4415 dtsi file is removed as nothing uses it.
- Intel PXA25x can now be booted using devicetree
Conflicts:
arch/arm/boot/dts/r8a*.dtsi: a node was added

dropping the required '};' at the end of each side.

Several SCIFB registers reside outside the reported register ranges.
Fortunately this works (on Linux), due to the PAGE_SIZE granularity of
