  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
  support additional fifth PHY::
    4 - MIPI CSIS 2.
