+* galaxycore,gc2093 MIPI sensor
+
+Required Properties:
+- compatible: should be "galaxycore,gc2093"
+- clocks: reference to the 24M 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: Low active reset gpio
+- pwdn-gpios: High active power-down gpio
