Subject: [PATCH v5 2/3] ARM: shmobile: lager: enable Ether

Signed-off-by: Simon Horman <horms+renesas@...ge.net.au>

---

This patch has a run-time dependency on "sh_eth: add support for r8a7790 SoC".

v5
* As suggested by Laurent Pinchart
  - Do not use eth_magic pinmux group, that pin is not used on Lager
* As suggested by Morimoto-san and Magnus Damm
  - Refactor moving all setup code into boards-lager.c

v4
* Remove needs_gpio_reset and reset_gpio from ether_platdata
  as the patch that adds that feature and those fields has
  been dropped.
* Annotate ether_platdata as __initdata

v3
* Use newly added "r8a7790-ether" instead of "sh-eth"

v2
* Do not add MSTP812, EtherAVB. It is not used.
* As suggested by Sergei Shtylyov <sergei.shtylyov@...entembedded.com>
  - Move Ethernet element of MSTP enum to a separate line
  - Move declaration of r8a7790_add_ether_device() to immediately
    after that of r8a7790_add_standard_devices()
  - Add __initdata annotation to ether_resource.
* As suggested by Laurent Pinchart
  - Do not manipilate sh_eth reset GPIO directly,
    rather, do so through newly proposed support for this in
    the sh_eth driver.
* A suggested by Sergei Shtylyov
  - Move DTS portion into a separate patch
