On some Allwinner SoCs, the EMAC clock register is in another device's emory space, e.g. on A64 it's in the memory space of SRAM controller.
This patchset adds the possibility for the device to export the EMAC clock register as a single-register regmap. PATCH 1 adds the device tree binding for dwmac-sun8i to use another device's regmap. PATCH 2 and 3 are dwmac-sun8i refactors. PATCH 4 exports the EMAC clock regmap in the SRAM controller driver. PATCH 5 enable SRAM controller in the A64 device tree (replaces syscon), and bind dwmac-sun8i to it.
