Subject: [PATCH 3/3] ASoC: dt-bindings: maxim,max98357a: Convert to DT schema
Convert the Maxim Integrated MAX98357A/MAX98360A amplifier bindings to
DT schema. Add missing properties ('#sound-dai-cells' and
'sound-name-prefix' from common DAI properties).
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

As a maintainer I added recent contributor to this driver/bindings:
Tzung-Bi Shih. Please ack if you agree to keep an eye on the bindings.

-Maxim MAX98357A/MAX98360A audio DAC
-
-This node models the Maxim MAX98357A/MAX98360A DAC.
-
-Required properties:
-- compatible : "maxim,max98357a" for MAX98357A.
- "maxim,max98360a" for MAX98360A.
-
-Optional properties:
-- sdmode-gpios : GPIO specifier for the chip's SD_MODE pin.
- If this option is not specified then driver does not manage
- the pin state (e.g. chip is always on).
-- sdmode-delay : specify delay time for SD_MODE pin.
- If this option is specified, which means it's required i2s clocks
- ready before SD_MODE is unmuted in order to avoid the speaker pop noise.
- It's observed that 5ms is sufficient.
-
-Example:
-
-max98357a {
- compatible = "maxim,max98357a";
- sdmode-gpios = <&qcom_pinmux 25 0>;
-};
-
-max98360a {
- compatible = "maxim,max98360a";
- sdmode-gpios = <&qcom_pinmux 25 0>;
-};
