Subject: [PATCH 1/8] mfd: dt-bindings: ti,twl4030-audio: convert to DT schema
Convert the legacy TXT binding for the TWL4030 audio module
to the modern YAML DT schema format. This adds formal validation
and improves documentation.

-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 {

-
- ti,enable-vibra = <1>;
-
- codec {
- ti,ramp_delay_value = <3>;
- };
-
- };
- };
