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.
