Subject: [RFC PATCH v2 0/5] ARM64: Add Internal PHY support for Meson GXL

The Amlogic Meson GXL SoCs have an internal RMII PHY that is muxed with the
external RGMII pins.

In order to support switching between the two PHYs links, extended registers
size for mdio-mux-mmioreg must be added.

Finally, the internal PHY is added in the GXL dtsi and support for each
board is added in intermediate board family dtsi or final dts.

This patchset depends on ARM64 dts patch at [1]

Changes since original RFC patchset at : [2]
 - Remove meson8b experimental phy switching
 - Switch to mdio-mux-mmioreg with extennded size support
 - Add internal phy support for S905x and p231
 - Add external PHY support for p230
