[PATCH RFC 0/8] Add R8A7743/SK-RZG1M board support

[PATCH RFC 0/8] Add R8A7743/SK-RZG1M board support

[Sergei Shtylyov]

Hello.

   Here's the set of 8 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20160916-v4.8-rc6' tag. I'm adding the device tree support for
the R8A7743-based SK-RZG1M board. The SoC is close to R8A7791 and the board
seems  identical to the R8A7791/Porter board. Only serial console is supported
for now, no DHCP/NFS support yet, it will be done RSN... :-)

[1/8] ARM: shmobile: r8a7743: add clock index macros
[2/8] ARM: shmobile: r8a7743: add power domain index macros
[3/8] soc: renesas: rcar-sysc: add R8A7743 support
[4/8] ARM: shmobile: r8a7743: basic SoC support
[5/8] ARM: dts: r8a7743: initial SoC device tree
[6/8] ARM: dts: r8a7743: add SYS-DMAC support
[7/8] ARM: dts: r8a7743: add [H]SCIF support
[8/8] ARM: dts: sk-rzg1m: initial device tree

WBR, Sergei

[PATCH RFC 1/8] ARM: shmobile: r8a7743: add clock index macros

[Sergei Shtylyov]

Add macros usable by the device tree sources to reference the R8A7743
clocks  by index.

Based on the original (and large) patch by Dmitry Shifrin
<dmitry.shifrin@cogentembedded.com>.

[PATCH RFC 8/8] ARM: dts: sk-rzg1m: initial device tree

[Sergei Shtylyov]

Add the initial device  tree for the R8A7743 SoC based SK-RZG1M board.
The board has one debug serial port (SCIF0); include support for it, so
that  the serial  console  can work.

Based on the original (and large) patch by Dmitry Shifrin
<dmitry.shifrin@cogentembedded.com>.

For a new SoC family, I would strongly suggest using a renesas,cpg-mssr
based binding instead:
  - No more mstp*_clocks nodes with array triplets to keep in sync,
  - Support for MSSR reset can be added later,
  - No need to add all those fixed-factor clocks to DT,
  - Less DT churn when adding support for new devices.
