+description:
+  The SENINF CD-PHY is a set of CD-PHY connected to the SENINF CSI-2
+  receivers. The number of PHYs depends on the SoC model.
+  Depending on the SoC model, each PHYs can be either CD-PHY or D-PHY only
+  capable.

+      If the PHY doesn't support mode selection then #phy-cells must be 0 and

+      If the PHY supports mode selection, then #phy-cells must be 1 and mode
