Please explain in the changelog why this is not a generic
phy driver (or three of them).

        Actually we tried to put the PHY code into Linux PHY framework.
        But it cannot fit in Linux common PHY framework.

        Our Xenon SDHC PHY register is a part of Xenon SDHC register set.
        Besides, during MMC initialization, MMC sequence has to call several PHY functions to complete timing setting.
        In those PHY setting functions, they have to access SDHC register and know current MMC setting, such as bus width, clock frequency and speed mode.
        As a result, we have to implement PHY under MMC directory.

Ok, that makes sense, just put the same text in the changelog comment.
