1Texas Instruments TWL family (twl4030) audio module
2
3The audio module inside the TWL family consist of an audio codec and a vibra
4driver.

11Audio 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
22Vibra 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.

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			};

44		};
45	};
