    Subject[PATCH 0/2] Add a regmap to Allwinner R40 CCU to export GMAC register
    Date
    In the CCU of the Allwinner R40 SoC, there's a GMAC configuration register,
    which is intended to be accessed by the dwmac-sun8i driver. On SoCs already
    supported by the driver the register is placed in the syscon rather than
    the CCU.

    As CCU is a critical part of the SoC, so write to it should be strictly
    limited. A regmap with restricted write permission is created by the R40
    CCU driver, and can be get with dev_get_regmap. In order to tie the regmap
    to the CCU device, the R40 CCU is now a platform driver, so a platform
    device is created for it (and then tied with the regmap).

    The first patch does the conversion of the driver to a platform driver,
    and the second patch adds the regmap.

    clk: sunxi-ng: r40: export a regmap to access the GMAC register
