Hi Olof, Hi Kevin, Hi Arnd,

Please consider these second round of Renesas ARM64 based SoC DT updates
for v4.16.

This pull request is based on the previous round of
such requests, tagged as renesas-arm64-dt-for-v4.16,
which you have already pulled.


The following changes since commit 8aba250d7800702bbd2f6a91174e01b9a84ed2dd:

  arm64: dts: renesas: r8a77970: use SYSC power domain macros (2017-12-05 09:30:48 +0100)

  arm64: dts: renesas: salvator-common: enable usb3_peri0 (2017-12-21 10:22:12 +0100)

----------------------------------------------------------------
Second Round of Renesas ARM64 Based SoC DT Updates for v4.16

* Add usb3_phy node to r8a7795 (R-Car H3) and r8a7796 (R-Car M3-W) SoCs, and
  enable usb3_peri0 on salvator boards

* Allow DTBs of boards of r8a7795 (R-Car H3) and r8a7796 SoCs to build
  without any warnings when compiled with W=1 using gcc-linaro-5.4.1-2017.05
  - Move nodes which have no reg property out of bus, they don't belong there
  - Add reg properties to dummy pciec[01] nodes
  - Also sort sub-nodes of root node to allow for easier maintenance

* Add Add EthernetAVB PHY reset to r8a7795 (R-Car H3) and r8a7796 SoCs boards.

  Geert Uytterhoeven says "... add properties to describe the EthernetAVB
  PHY reset topology to the common Salvator-X/XS and ULCB DTS files, which
  solves two issues:
    1. On Salvator-XS, the enable pin of the regulator providing PHY power
       is connected to PRESETn, and PSCI powers down the SoC during system
       suspend.  Hence a PHY reset is needed to restore network
       functionality after system resume.
    2. Linux should not rely on the boot loader having reset the PHY, but
       should reset the PHY during driver probe."
