| 2 | |
| 3 | Required properties: |
| 4 | - compatible: "amlogic,g12a-tohdmitx" or |
| 5 | "amlogic,sm1-tohdmitx" |
| 6 | - reg: physical base address of the controller and length of memory |
| 7 | mapped region. |
| 8 | - #sound-dai-cells: should be 1. |
| 9 | - resets: phandle to the dedicated reset line of the hdmitx glue. |
| 10 | |
| 11 | Example on the S905X2 SoC: |
| 12 | |
| 13 | tohdmitx: audio-controller@744 { |
| 14 | compatible = "amlogic,g12a-tohdmitx"; |
| 15 | reg = <0x0 0x744 0x0 0x4>; |
| 16 | #sound-dai-cells = <1>; |
| 17 | resets = <&clkc_audio AUD_RESET_TOHDMITX>; |
| 18 | }; |
| 19 | |
| 20 | Example of an 'amlogic,axg-sound-card': |
| 21 | |
| 22 | sound { |
| 23 | compatible = "amlogic,axg-sound-card"; |
| 24 | |
| 25 | [...] |
| 26 | |
| 27 | dai-link-x { |
| 28 | sound-dai = <&tdmif_a>; |
| 29 | dai-format = "i2s"; |
| 30 | dai-tdm-slot-tx-mask-0 = <1 1>; |
| 31 | |
| 32 | codec-0 { |
| 33 | sound-dai = <&tohdmitx TOHDMITX_I2S_IN_A>; |
| 34 | }; |
| 35 | |
| 36 | codec-1 { |
| 37 | sound-dai = <&external_dac>; |
| 38 | }; |
| 39 | }; |
| 40 | |
| 41 | dai-link-y { |
| 42 | sound-dai = <&tdmif_c>; |
| 43 | dai-format = "i2s"; |
| 44 | dai-tdm-slot-tx-mask-0 = <1 1>; |
| 45 | |
| 46 | codec { |
| 47 | sound-dai = <&tohdmitx TOHDMITX_I2S_IN_C>; |
| 48 | }; |
| 49 | }; |
| 50 | |
| 51 | dai-link-z { |
| 52 | sound-dai = <&tohdmitx TOHDMITX_I2S_OUT>; |
| 53 | |
| 54 | codec { |
| 55 | sound-dai = <&hdmi_tx>; |
| 56 | }; |
| 57 | }; |
| 58 | }; |
