This serie converts Allwinner A20 (sun7i) GMAC driver to CCU while still retaining compatibility with existing devicetrees. First two patches contain preliminary work which convert sun4i/sun7i clock drivers to platform devices and creates regmap to access gmac register from the sun7i gmac driver. Third patch implements syscon-based regmap to allow driver manage its own clock source. Fourth patch updates the devicetree and drops the unused clocks. While testing the driver I noticed following bugs with the existing sun7i gmac driver: - driver relies on u-boot for initialization (fixed in this implementation) - `systemctl restart networking` fails to bring the link up again.
