The ADV7604 has four multiplexed HDMI inputs and one analog 15 input, and the ADV7611 has one HDMI input and no analog input. The 7612 is 16 similar to the 7611 but has 2 HDMI inputs. 17 18 These device tree bindings support the ADV7611/12 only at the moment. 19 20properties: 21 compatible: 22 items: 23 - enum: 24 - adi,adv7611 25 - adi,adv7612 26 27 reg: 28 minItems: 1 29 maxItems: 13 30 31 reg-names: 32 minItems: 1 33 items: 34 - const: main 35 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 36 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 37 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 38 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 39 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 40 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 41 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 42 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 43 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 44 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 45 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 46 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 47 48 interrupts: 49 maxItems: 1 50 51 reset-gpios: 52 maxItems: 1 53 54 hpd-gpios: 55 minItems: 1 56 description: 57 References to the GPIOs that control the HDMI hot-plug detection pins, 58 one per HDMI input.
