+description: |
+  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.
