1Texas Instruments TWL family (twl4030) audio module2 3The audio module inside the TWL family consist of an audio codec and a vibra4driver.5 6Required properties:7- compatible : must be "ti,twl4030-audio"8 9Optional properties, nodes:10 11Audio functionality:12- codec { }: Need to be present if the audio functionality is used. Within this13 section the following options can be used:14- ti,digimic_delay: Delay need after enabling the digimic to reduce artifacts15 from the start of the recorded sample (in ms)16-ti,ramp_delay_value: HS ramp delay configuration to reduce pop noise17-ti,hs_extmute: Use external mute for HS pop reduction18-ti,hs_extmute_gpio: Use external GPIO to control the external mute19-ti,offset_cncl_path: Offset cancellation path selection, refer to TRM for the20 valid values.21 22Vibra functionality23- ti,enable-vibra: Need to be set to <1> if the vibra functionality is used. if24 missing or it is 0, the vibra functionality is disabled.25 26Example: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};47
