phy: exynos-mipi-video: Add support for Exynos 5420 and 5433 SoCs
This patch adds support for MIPI DPHYs found in Exynos5420-compatible (5420, 5422 and 5800) and Exynos5433 SoCs. Those SoCs differs from earlier by different offset of MIPI DPHY registers in PMU controllers (Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to separate system register controllers (Exynos 5433 case). In both case also additional 5th PHY (MIPI CSIS 2) has been added.
