[PATCH v8 0/4] Add ethernet support for r7s72100

[PATCH v8 0/4] Add ethernet support for r7s72100

[Simon Horman]

From: Simon Horman <horms@verge.net.au>

Hi,

this series integrates ethernet support to sh-pfc for the r7s72100 SoC
and Genmai board.

This series is based on renesas-devel-v3.14-rc1-20140204
but patches from topic/r7s72100-v3.14-rc1-20140206 are required
in order to boot the Genmai board.


There are no changes to these patches since v7,
however driver patches included in that series have
been dropped as they are present in v3.14-rc1.

Simon Horman (2):
  ARM: shmobile: r7s72100: Add clock for r7s72100-ether
  ARM: shmobile: genmai: Enable r7s72100-ether

v6 - v8
* No change

v5
* Rebase

v3 - v4
* No change

v2
* As suggested by Sergei Shtylyov
  - Add MSTP74 to beginning of enum on a line by itself
* As suggested by Magnus Damm
  - r7s72100 ethernet is not gigabit so do not refer to it as such

  - r7s72100 ethernet is not gigabit so do not refer to it as such

* As suggested by Sergei Shtylyov
  - set no_ether_link as there is no LINK signal documented
    in the manual
