* RK628 HDMI-RX to MIPI CSI2-TX Bridge
The RK628 HDMI-RX to MIPI CSI2-TX (H2C) is a bridge that converts
a HDMI stream to MIPI CSI-2 TX. It is programmable through I2C.
Required Properties:
- compatible: value should be "rockchip,rk628-csi-v4l2"
- reg: I2C device address
Optional Properties:
- reset-gpios: gpio phandle GPIO connected to the reset pin
- enable-gpios: a GPIO spec for the enable pin
- plugin-det-gpios: HDMI 5V detect pin
- interrupts: GPIO connected to the interrupt pin
- data-lanes: should be <1 2 3 4> for four-lane operation,
or <1 2> for two-lane operation
For further information on the MIPI CSI-2 endpoint node properties, see
Documentation/devicetree/bindings/media/video-interfaces.txt.
Example:
rk628_csi_v4l2: rk628_csi_v4l2@50 {
reg = <0x50>;

interrupts = <2 IRQ_TYPE_LEVEL_HIGH>;
enable-gpios = <&gpio5 RK_PC3 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio2 RK_PA3 GPIO_ACTIVE_LOW>;
plugin-det-gpios = <&gpio2 RK_PA4 GPIO_ACTIVE_LOW>;
