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::
24    4 - MIPI CSIS 2.
