+BOE HV070WSA-100 7.01" WSVGA TFT LCD panel
+
+Required properties:
+- compatible: should be "boe,hv070wsa-100"
+- power-supply: regulator to provide the VCC supply voltage (3.3 volts)
+- enable-gpios: GPIO pin to enable and disable panel (active high)
+
+This binding is compatible with the simple-panel binding, which is specified
+in simple-panel.txt in this directory.
+
+The device node can contain one 'port' child node with one child
+'endpoint' node, according to the bindings defined in [1]. This
+node should describe panel's video bus.

+Example:
+
+       panel: panel {
+               compatible = "boe,hv070wsa-100";
+               power-supply = <&vcc_3v3_reg>;
+               enable-gpios = <&gpd1 3 GPIO_ACTIVE_HIGH>;
+               port {
+                       panel_ep: endpoint {
+                               remote-endpoint = <&bridge_out_ep>;
