0001 Texas Instruments TWL family (twl4030) audio module
0002
0003 The audio module inside the TWL family consist of an audio codec and a vibra
0004 driver.
0005
0006 Required properties:
0007 - compatible : must be "ti,twl4030-audio"
0008
0009 Optional properties, nodes:
0010
0011 Audio functionality:
0012 - codec { }: Need to be present if the audio functionality is used. Within this
0013 section the following options can be used:
0014 - ti,digimic_delay: Delay need after enabling the digimic to reduce artifacts
0015 from the start of the recorded sample (in ms)
0016 -ti,ramp_delay_value: HS ramp delay configuration to reduce pop noise
0017 -ti,hs_extmute: Use external mute for HS pop reduction
0018 -ti,hs_extmute_gpio: Use external GPIO to control the external mute
0019 -ti,offset_cncl_path: Offset cancellation path selection, refer to TRM for the
0020 valid values.
0021
0022 Vibra functionality
0023 - ti,enable-vibra: Need to be set to <1> if the vibra functionality is used. if
0024 missing or it is 0, the vibra functionality is disabled.
0025
0026 Example:
0027 &i2c1 {
0028 clock-frequency = <2600000>;
0029
0030 twl: twl@48 {
0031 reg = <0x48>;
0032 interrupts = <7>; /* SYS_NIRQ cascaded to intc */
0033 interrupt-parent = <&intc>;
0034
0035 twl_audio: audio {
0036 compatible = "ti,twl4030-audio";
0037
0038 ti,enable-vibra = <1>;
0039
0040 codec {
0041 ti,ramp_delay_value = <3>;
0042 };
0043
0044 };
0045 };
0046 };
