-------------------------------------------------



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.
