The initial staging driver however only supported D-PHY and the bus-type property was left optional. In preparation for adding C-PHY support to the staging driver make the bus-type property mandatory as it is needed to select the correct PHY mode. Without the bus-type property present, the driver falls-back to D-PHY mode, so the change is functionally backward compatible with old DTS files lacking the property. The only in-tree DTS file (renesas/r8a779a0-falcon-csi-dsi.dtsi) that lacked the property uses D-PHY and have been updated.
