786a72d791 ARM: DT updates for v4.10
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
 the clk tree, keep both sides and watch out for git
 dropping the required '};' at the end of each side.

08344f3b43 ARM: SoC: late DT updates for v4.7
This is a collection of a few late fixes and other misc. stuff that
 had dependencies on things being merged from other trees.
 
 The Renesas R-Car power domain handling, and the Nvidia Tegra USB
 support both hand notable changes that required changing the DT binding
 in a way that only provides compatibility with old DT blobs on new
 kernels but not vice versa. As a consequence, the DT changes
 are based on top of the driver changes and are now in this branch.
 
 For NXP i.MX and Samsung Exynos, the changes in here depend on
 other changes that got merged through the clk maintainer tree.

57f9156bc6 ARM: dts: r8a7793: enable to use thermal-zone
This patch enables to use thermal-zone on r8a7793.
This thermal sensor can measure temperature from -40000 to 125000,
but over 117000 can be critical on this chip.
Thus, default critical temperature is now set as 115000 (this driver
is using 5000 steps) (Current critical temperature is using it as
90000, but there is no big reason about it)

And it doesn't check thermal zone periodically (same as current
behavior). You can exchange it by modifying polling-delay[-passive]
property.

You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS,
but you need to take care to use it, since it will call
orderly_poweroff() it it reaches to the value.
echo $temp > /sys/class/thermal/thermal_zone0/trip_point_0_temp

166d8ca693 ARM: dts: r8a7793: Add BRG support for SCIF
Add the device node for the external SCIF_CLK.
The presence of the SCIF_CLK crystal and its clock frequency depends on
the actual board.

Add the two optional clock sources (ZS_CLK and SCIF_CLK for the internal
resp. external clock) for the Baud Rate Generator for External Clock
(BRG) to all SCIF and HSCIF device nodes.

This increases the range and accuracy of supported baud rates on
(H)SCIF.

Use the new SoC specific binding for rcar-dmac and the generic
binding as a fall-back in the r8a7793 device tree.

In general Renesas hardware is not documented to the extent where the
relationship between IP blocks on different SoCs can be assumed although
they may appear to operate the same way. Furthermore the documentation
typically does not specify a version for individual IP blocks. For these
reasons a convention of using the SoC name in place of a version and
providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings for
most drivers for Renesas hardware. The purpose of this patch is to
update the Renesas R-Car DMA Controller nodes to follow this convention.

This has been confirmed by reading the GICD_IIDR register (on r8a7791),
which reports 0x0200043b (GIC-400 = 0x02, ARM = 0x43b).

This has no effect on runtime behavior, as currently the GIC driver
