[PATCH 1/3] arm64: dts: rockchip: Remove unnecessary reset in rk3328.dtsi

[Ezequiel Garcia]

Rockchip DWMAC glue driver uses the phy node (phy-handle)
reset specifier, and not a "mac-phy" reset specifier.

Remove it.

[PATCH 2/3] dt-bindings: net: dwmac: Add Rockchip DWMAC support

[Ezequiel Garcia]

Add Rockchip DWMAC controllers, which are based on snps,dwmac.
Some of the SoCs require up to eight clocks, so maxItems
for clocks and clock-names need to be increased.

No you don't because there isn't 'snps,dwmac' in the compatible.

range, default, those are constraints. Make a schema.
