Hi Arnd, Olof,

Sorry for submitting this short series so late. I was waiting for the clk
patches to be picked by Stephen.

For the Actions ARM32 platform, we have just couple of patches for v5.14 cycle
adding Ethernet support to the S500 SoC and enabling it on the Roseapple Pi dev
board. The EMAC controller is an in-house IP from Actions Semi capable of
operating at 10/100Mb/s in half-duplex and full-duplex modes. The emac driver
patches are already merged into netdev and the clk patches are just queued for
v5.14.

The ethernet node depends on the clk binding update for which the patch has
already been merged into clk tree[1].

Please consider applying!

Thanks,
Mani

Add pinctrl configuration for enabling the Ethernet MAC on RoseapplePi
SBC. Additionally, provide the necessary properties for the generic S500
ethernet node in order to setup PHY and MDIO.
