Texas Instruments TWL family (twl4030) audio module
|
|
The audio module inside the TWL family consist of an audio codec and a vibra
|
driver.
|
|
Required properties:
|
- compatible : must be "ti,twl4030-audio"
|
|
Optional properties, nodes:
|
|
Audio functionality:
|
- codec { }: Need to be present if the audio functionality is used. Within this
|
section the following options can be used:
|
- ti,digimic_delay: Delay need after enabling the digimic to reduce artifacts
|
from the start of the recorded sample (in ms)
|
-ti,ramp_delay_value: HS ramp delay configuration to reduce pop noise
|
-ti,hs_extmute: Use external mute for HS pop reduction
|
-ti,hs_extmute_gpio: Use external GPIO to control the external mute
|
-ti,offset_cncl_path: Offset cancellation path selection, refer to TRM for the
|
valid values.
|
|
Vibra functionality
|
- ti,enable-vibra: Need to be set to <1> if the vibra functionality is used. if
|
missing or it is 0, the vibra functionality is disabled.
|
|
Example:
|
&i2c1 {
|
clock-frequency = <2600000>;
|
|
twl: twl@48 {
|
reg = <0x48>;
|
interrupts = <7>; /* SYS_NIRQ cascaded to intc */
|
interrupt-parent = <&intc>;
|
|
twl_audio: audio {
|
compatible = "ti,twl4030-audio";
|
|
ti,enable-vibra = <1>;
|
|
codec {
|
ti,ramp_delay_value = <3>;
|
};
|
|
};
|
};
|
};
