 15  For samsung,s5pv210-mipi-video-phy compatible PHYs the second cell in the
 16  PHY specifier identifies the PHY and its meaning is as follows::
 17    0 - MIPI CSIS 0,
 18    1 - MIPI DSIM 0,
 19    2 - MIPI CSIS 1,
 20    3 - MIPI DSIM 1.
 21
 22  samsung,exynos5420-mipi-video-phy and samsung,exynos5433-mipi-video-phy
 23  support additional fifth PHY::
