+* galaxycore,gc4c33 MIPI sensor
+
+Required Properties:
+- compatible: should be "galaxycore,gc4c33"
+- clocks: reference to the 27M xvclk input clock.
+- clock-names: should be "xvclk".
+- dovdd-supply: Digital I/O voltage supply, 1.8 volts
+- avdd-supply: Analog voltage supply, 2.8 volts
+- dvdd-supply: Digital core voltage supply, 1.2 volts
+- reset-gpios: High active reset gpio
