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>; |
|
}; |
|
|
|
}; |
|
}; |
