1* Analog Devices ADV7604/11/12 video decoder with HDMI receiver 2 3The ADV7604 and ADV7611/12 are multiformat video decoders with an integrated 4HDMI receiver. The ADV7604 has four multiplexed HDMI inputs and one analog 5input, and the ADV7611 has one HDMI input and no analog input. The 7612 is 6similar to the 7611 but has 2 HDMI inputs. 7 8These device tree bindings support the ADV7611/12 only at the moment. 9 10Required Properties: 11 12 - compatible: Must contain one of the following 13 - "adi,adv7611" for the ADV7611 14 - "adi,adv7612" for the ADV7612 15 16 - reg: I2C slave address 17 18 - hpd-gpios: References to the GPIOs that control the HDMI hot-plug 19 detection pins, one per HDMI input. The active flag indicates the GPIO 20 level that enables hot-plug detection. 21 22The device node must contain one 'port' child node per device input and output 23port, in accordance with the video interface bindings defined in 24Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes 25are numbered as follows. 26 27 Port ADV7611 ADV7612 28------------------------------------------------------------ 29 HDMI 0 0, 1 30 Digital output 1 2 31 32The digital output port node must contain at least one endpoint. 33 34Optional Properties: 35 36 - reset-gpios: Reference to the GPIO connected to the device's reset pin. 37 38Optional Endpoint Properties: 39 40 The following three properties are defined in video-interfaces.txt and are 41 valid for source endpoints only. 42 43 - hsync-active: Horizontal synchronization polarity. Defaults to active low. 44 - vsync-active: Vertical synchronization polarity. Defaults to active low. 45 - pclk-sample: Pixel clock polarity. Defaults to output on the falling edge. 46 47 If none of hsync-active, vsync-active and pclk-sample is specified the 48 endpoint will use embedded BT.656 synchronization. 49 50 - default-input: Select which input is selected after reset. 51 52Example: 53 54 hdmi_receiver@4c { 55 compatible = "adi,adv7611"; 56 reg = <0x4c>; 57 58 reset-gpios = <&ioexp 0 GPIO_ACTIVE_LOW>; 59 hpd-gpios = <&ioexp 2 GPIO_ACTIVE_HIGH>; 60 61 #address-cells = <1>; 62 #size-cells = <0>; 63 64 default-input = <0>; 65 66 port@0 { 67 reg = <0>; 68 }; 69 port@1 { 70 reg = <1>; 71 hdmi_in: endpoint { 72 remote-endpoint = <&ccdc_in>; 73 }; 74 }; 75 }; 76
