    1 Texas Instruments TWL family (twl4030) audio module
    2 
    3 The audio module inside the TWL family consist of an audio codec and a vibra
    4 driver.
    5 
    6 Required properties:
    7 - compatible : must be "ti,twl4030-audio"
    8 
    9 Optional properties, nodes:
   10 
   11 Audio 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 
   22 Vibra 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.
   25 
   26 Example:
   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 };
