    SubjectRe: [PATCHv2 2/3] drm: exynos: hdmi: use hdmiphy as PHY
    Hi Andrzej,
    This issue could be solved by exporting a regmap from PMU driver
    or Exynos clock provider for the usage by exynos-simple-phy.
    The operations on PHYs from exynos-simple-phy provider would
    be chained to PMU driver and protected by a spinlock in the regmap.

    Luckily, the divider is not used as far as I know.

    Regards,
    Tomasz Stanislawski
