-Samsung S5P/Exynos SoC series MIPI CSIS/DSIM DPHY
--------------------------------------------------
-
-Required properties:
-- compatible : should be one of the listed compatibles:
-	- "samsung,s5pv210-mipi-video-phy"
-	- "samsung,exynos5420-mipi-video-phy"
-	- "samsung,exynos5433-mipi-video-phy"
-- #phy-cells : from the generic phy bindings, must be 1;
-
-In case of s5pv210 and exynos5420 compatible PHYs:
-- syscon - phandle to the PMU system controller
-
-In case of exynos5433 compatible PHY:
- - samsung,pmu-syscon - phandle to the PMU system controller
- - samsung,disp-sysreg - phandle to the DISP system registers controller
- - samsung,cam0-sysreg - phandle to the CAM0 system registers controller
- - samsung,cam1-sysreg - phandle to the CAM1 system registers controller
-
-For "samsung,s5pv210-mipi-video-phy" compatible PHYs the second cell in
-the PHY specifier identifies the PHY and its meaning is as follows:
-  0 - MIPI CSIS 0,
-  1 - MIPI DSIM 0,
-  2 - MIPI CSIS 1,
-  3 - MIPI DSIM 1.
-"samsung,exynos5420-mipi-video-phy" and "samsung,exynos5433-mipi-video-phy"
-supports additional fifth PHY:
-  4 - MIPI CSIS 2.
