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.
