1 Texas Instruments TWL family (twl4030) audio module
3 The audio module inside the TWL family consist of an audio codec and a vibra
7 - compatible : must be "ti,twl4030-audio"
9 Optional properties, nodes:
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
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.
