The ADV7604 has four multiplexed HDMI inputs 15 and one analog input, and the ADV7610/11 have one HDMI input and no analog 16 input. The ADV7612 is similar to the ADV7610/11 but has 2 HDMI inputs. 17 18 These device tree bindings support the ADV7610/11/12 only at the moment. 19 20properties: 21 compatible: 22 items: 23 - enum: 24 - adi,adv7610 25 - adi,adv7611 26 - adi,adv7612 27 28 reg: 29 minItems: 1 30 maxItems: 13 31 32 reg-names: 33 minItems: 1 34 items: 35 - const: main 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 - enum: [ avlink, cec, infoframe, esdp, dpp, afe, rep, edid, hdmi, test, cp, vdp ] 48 49 interrupts: 50 maxItems: 1 51 52 reset-gpios: 53 maxItems: 1 54 55 hpd-gpios: 56 minItems: 1 57 description: 58 References to the GPIOs that control the HDMI hot-plug detection pins, 59 one per HDMI input.
