This serie converts Allwinner A20 and A31 GMAC driver to CCU while still retaining compatibility with existing devicetrees. This patchset touches 3 areas: - sun7i and sun6i CCUs now set up regmap to allow dwmac-sunxi driver to properly access the GMAC clock register. - dwmac-sunxi can now handle syscon-based clock register to handle clock itself. - sun7i and sun6i devicetrees are converted to use the new syscon-based access. Changes since v1: * Use CLK_OF_DECLARE_DRIVER to make it possible to probe again and set up regmap using platform device probe. * Clarify the meaning of "legacy" in dwmac-sunxi driver. * Make sure we don't mess with the RX/TX delay settings when updating clock registers. * Update devicetree bindings * Add sun6i-A31 support.
