+* GalaxyCore GC5035 MIPI sensor
+
+Required Properties:
+- compatible: should be "galaxycore,gc5035"
+- clocks: reference to the 24M xvclk input clock.
+- clock-names: should be "xvclk".
+- dovdd-supply: Digital I/O voltage supply, 1.7~3.0 volts
+- avdd-supply: Analog voltage supply, 2.8 volts
+- dvdd-supply: Digital core voltage supply, 1.2 volts
+- reset-gpios: Low active reset gpio
+- powerdown-gpios: Low active powerdown gpio
+
+Attention:
+GC5035 device address 0x6e(8bit) or 0x7e(8bit) is decided by IDSEL pin;
+
+The device node must contain one 'port' child node for its digital output
+video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
