2c25291762 Renesas ARM Based SoC DT Updates for v4.16
* Convert to named i2c-gpio bindings
 
   Geert Uytterhoeven says "Commits 7d29f509d2 ("dt-bindings: i2c:
   i2c-gpio: Add support for named gpios") and 05c7477885 ("i2c: gpio:
   Add support for named gpios in DT") introduced named i2c-gpio DT
   bindings, and deprecated the more error-prone unnamed variant.
 
   This patch series switches all Renesas boards to the new bindings, and
   adds the missing GPIO_OPEN_DRAIN I/O flags, which were implicitly
   assumed before..."
 
   ...  Note that after this series is applied, the i2c-gpio buses are no
   longer detected when booting new DTBs on old (v4.14 and older) kernels,
   which should not be an issue.  Booting old DTBs on new kernels is not
   affected."
 
 * Update DTS for CMT DT binding rework
 
   Geert Uytterhoeven says "This patch series updates the CMT device nodes
   in the various Renesas DTS files sh_cmt clocksource driver for the recent
   DT binding rework that was merged in v4.14-rc1 and v4.15-rc1..."
 
 * Add SMP support to r8a7794 (R-Car E2) SoC
 
   Sergei Shtylyov says "Add the device tree node for the Advanced Power
   Management Unit (APMU).  Use the "enable-method" prop to  point out that
   the APMU should be used for the SMP support."
 
 * Correct primary compatible value for eeprom
   on r7s72100 (RZ/A1H) genmai and r8a7791 (R-Car M2-W) koelsh boards
 
   Geert Uytterhoeven says "The Renesas part numbers of the two-wire serial
   interface EEPROMs do not follow the 24Cxx pattern, but the R1EX24xxx
   pattern.
 
   Hence change the primary compatible values to the appropriate variant of
   "renesas,r1ex24xxx", like is already done on Gose.""
 
 * Move cec_clock to root node on r8a7791 (R-Car M2-W) koelsh board
   r8a7791 (R-Car M2-W) koelsh board
 
 * Use R-Car SDHI and Ether Gen1 and 2 fallback compat strings
 
   Use recently posted R-Car SDHI and Ether Gen 1 and 2 fallback
   compat strings in the DT of Renesas ARM based SoCs.
 
 * Add IIC cores to dtsi of r8a7745 (RZ/G1E) SoC
 
 * Rework DT architecture for r8a7745 (RZ/G1E) iW-RainboW-G22D development
   platform and add serial support.
 
   Fabrizio Castro says "... define a new DT architecture for the
   iW-RainboW-G22D SODIMM Development Platform to include the configuration
   with the HDMI daughter board and to define the serial interfaces."
 
 * Add USB function support to
   r8a7745 (RZ/G1E) iW-RainboW-G22D development platform

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.

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.

40a99dbb99 ARM: dts: r8a7794: Use R-Car Gen 2 fallback binding for iic nodes
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.

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

 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.

Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC late DT updates from Arnd Bergmann:
 "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

25611e4ef5 ARM: dts: r8a7794: Use SYSC "always-on" PM Domain
Hook up all devices that are part of the CPG/MSTP Clock Domain to the
SYSC "always-on" PM Domain, for a more consistent device-power-area
description in DT.

c9006ac628 ARM: dts: r8a7794: Don't disable referenced optional clocks
clk_get() on a disabled clock node will return -EPROBE_DEFER, which can
cause drivers to be deferred forever if such clocks are referenced in
their devices' clocks properties.

Update the various disabled external clock nodes to default to a
frequency of 0, but don't disable them, to prevent this.
