Sylwester Nawrocki e4b3d38088 phy: exynos-video-mipi: Fix regression by adding support for PMU regmap ... After the Exynos Power Management Unit (PMU) driver was converted to the platform device driver in commit 14fc8b93d4 ("ARM: EXYNOS: Add platform driver support for Exynos PMU") and then PMU device nodes added to Exynos4 DTs in commit 7b9613aca4 ("ARM: dts: add PMU syscon node for exynos4") the mipi video phy driver started failing probing, due to overlapping memory mapped register region resources. Now all the Exynos peripheral devices which have registers in the PMU region are supposed to use the regmap provided by the syscon driver. So support for regmap is added in this patch, this unfortunately creates yet another indirection into that supposedly trivial driver. The additional mutex is required because single register is used by PHY pairs (they share bit in a register). An improvement here could be to allow a PHY instance be created with a driver custom mutex, which would then be common for each PHY pair. This would eliminate one of 3 mutexes which need to be taken in the phy_power_on/ phy_power_off code path. However, I tried to keep this bug fix patch possibly simple. This change is needed to make MIPI DSI displays and MIPI CSI-2 camera sensors working again on Exynos4 boards.
