[PATCH v4 0/2] Add ethernet support for Meson-AXG SoC

[Yixun Lan]

This series try to add support for the ethernet MAC controller
found in Meson-AXG SoC, and also enable it in the S400 board.

Hi Kevin:
  You still need to at least merge the clock patch[3] in order to
compile the DTS, or just merge the tag from meson-clock's tree[6]
- the tag is 'meson-clk-for-v4.16-2', since the clock part already
taken there.


Changes in v4 since [5]:
 - rebase to kevin's v4.16/dt64
 - fix order

Changes in v3 since [4]:
 - put clock DT info in soc.dtsi
 - separate DT for 'add support for the controller' vs 'enable in board'

Changes in v2 since [1]:
 - rebase to kevin's v4.16/dt64 branch
 - add Neil's Reviewed-by
 - move clock info to board.dts instead of in soc.dtsi
 - drop "meson-axg-dwmac" compatible string, since we didn't use this
   we could re-add it later when we really need.
 - note: to make ethernet work properly,it depend on clock & pinctrl[2],
   to compile the DTS, the patch [3] is required.
   the code part will be taken via clock & pinctrl subsystem tree.

[PATCH v4 1/2] ARM64: dts: meson-axg: add ethernet mac controller

[Yixun Lan]

Add DT info for the stmmac ethernet MAC which found in
the Amlogic's Meson-AXG SoC, also describe the ethernet
pinctrl & clock information here.

[PATCH v4 2/2] ARM64: dts: meson-axg: enable ethernet for A113D S400 board

[Yixun Lan]

This is tested in the S400 dev board which use a RTL8211F PHY,
and the pins connect to the 'eth_rgmii_y_pins' group.
