| 2 | |
| 3 | The audio module inside the TWL family consist of an audio codec and a vibra |
| 4 | driver. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible : must be "ti,twl4030-audio" |
| 8 | |
| 9 | Optional properties, nodes: |
| 10 | |
| 11 | Audio functionality: |
| 12 | - codec { }: Need to be present if the audio functionality is used. Within this |
| 13 | section the following options can be used: |
| 14 | - ti,digimic_delay: Delay need after enabling the digimic to reduce artifacts |
| 15 | from the start of the recorded sample (in ms) |
| 16 | -ti,ramp_delay_value: HS ramp delay configuration to reduce pop noise |
| 17 | -ti,hs_extmute: Use external mute for HS pop reduction |
| 18 | -ti,hs_extmute_gpio: Use external GPIO to control the external mute |
| 19 | -ti,offset_cncl_path: Offset cancellation path selection, refer to TRM for the |
| 20 | valid values. |
| 21 | |
| 22 | Vibra functionality |
| 23 | - ti,enable-vibra: Need to be set to <1> if the vibra functionality is used. if |
| 24 | missing or it is 0, the vibra functionality is disabled. |
| 25 | |
| 26 | Example: |
| 27 | &i2c1 { |
| 28 | clock-frequency = <2600000>; |
| 29 | |
| 30 | twl: twl@48 { |
| 31 | reg = <0x48>; |
| 32 | interrupts = <7>; /* SYS_NIRQ cascaded to intc */ |
| 33 | interrupt-parent = <&intc>; |
| 34 | |
| 35 | twl_audio: audio { |
| 36 | compatible = "ti,twl4030-audio"; |
| 37 | |
| 38 | ti,enable-vibra = <1>; |
| 39 | |
| 40 | codec { |
| 41 | ti,ramp_delay_value = <3>; |
| 42 | }; |
| 43 | |
| 44 | }; |
| 45 | }; |
| 46 | }; |
