-* Analog Devices ADV7604/11/12 video decoder with HDMI receiver
-
-The ADV7604 and ADV7611/12 are multiformat video decoders with an integrated
-HDMI receiver. The ADV7604 has four multiplexed HDMI inputs and one analog
-input, and the ADV7611 has one HDMI input and no analog input. The 7612 is
-similar to the 7611 but has 2 HDMI inputs.
-
-These device tree bindings support the ADV7611/12 only at the moment.
-
-Required Properties:
-
- - compatible: Must contain one of the following
- - "adi,adv7611" for the ADV7611
- - "adi,adv7612" for the ADV7612
-
- - reg: I2C slave addresses
- The ADV76xx has up to thirteen 256-byte maps that can be accessed via the
- main I2C ports. Each map has it own I2C address and acts as a standard
- slave device on the I2C bus. The main address is mandatory, others are
- optional and revert to defaults if not specified.
-
-The device node must contain one 'port' child node per device input and output
-port, in accordance with the video interface bindings defined in
-Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
-are numbered as follows.
-
- Port ADV7611 ADV7612
-------------------------------------------------------------
- HDMI 0 0, 1
- Digital output 1 2
-
-The digital output port node must contain at least one endpoint.
-
-Optional Properties:
-
- - hpd-gpios: References to the GPIOs that control the HDMI hot-plug
- detection pins, one per HDMI input. The active flag indicates the GPIO
- level that enables hot-plug detection.
- - reset-gpios: Reference to the GPIO connected to the device's reset pin.
- - default-input: Select which input is selected after reset.
- - reg-names : Names of maps with programmable addresses.
- It can contain any map needing a non-default address.
- Possible maps names are :
- "main", "avlink", "cec", "infoframe", "esdp", "dpp", "afe",
- "rep", "edid", "hdmi", "test", "cp", "vdp"
-
-Optional Endpoint Properties:
-
- The following three properties are defined in video-interfaces.txt and are
- valid for source endpoints only.
-
- - hsync-active: Horizontal synchronization polarity. Defaults to active low.
- - vsync-active: Vertical synchronization polarity. Defaults to active low.
- - pclk-sample: Pixel clock polarity. Defaults to output on the falling edge.
-
- If none of hsync-active, vsync-active and pclk-sample is specified the
- endpoint will use embedded BT.656 synchronization.
-
-Example:
-
- hdmi_receiver@4c {
- compatible = "adi,adv7611";
- /*
- * The edid page will be accessible @ 0x66 on the I2C bus. All
- * other maps will retain their default addresses.
- */
- reg = <0x4c>, <0x66>;
- reg-names = "main", "edid";
-
- reset-gpios = <&ioexp 0 GPIO_ACTIVE_LOW>;
- hpd-gpios = <&ioexp 2 GPIO_ACTIVE_HIGH>;
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- default-input = <0>;
-
- port@0 {
- reg = <0>;
- };
- port@1 {
- reg = <1>;
- hdmi_in: endpoint {
- remote-endpoint = <&ccdc_in>;
- };
- };
- };
