-Texas Instruments - tlv320aic32x4 Codec module
-
-The tlv320aic32x4 serial control bus communicates through I2C protocols
-
-Required properties:
- - compatible - "string" - One of:
- "ti,tlv320aic32x4" TLV320AIC3204
- "ti,tlv320aic32x6" TLV320AIC3206, TLV320AIC3256
- "ti,tas2505" TAS2505, TAS2521
- - reg: I2C slave address
- - *-supply: Required supply regulators are:
- "iov" - digital IO power supply
- "ldoin" - LDO power supply
- "dv" - Digital core power supply
- "av" - Analog core power supply
- If you supply ldoin, dv and av are optional. Otherwise they are required
- See regulator/regulator.txt for more information about the detailed binding
- format.
-
-Optional properties:
- - reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt
- - clocks/clock-names: Clock named 'mclk' for the master clock of the codec.
- See clock/clock-bindings.txt for information about the detailed format.
- - aic32x4-gpio-func - <array of 5 int>
- - Types are defined in include/sound/tlv320aic32x4.h
-
-
-Example:
-
-codec: tlv320aic32x4@18 {
- compatible = "ti,tlv320aic32x4";
- reg = <0x18>;
- clocks = <&clks 201>;

Convert the binding to DT schema format. Since commit 514b044cba667 ("ASoC: tlv320aic32x4: Model PLL in CCF") clocks & clock-names = "mclk" is mandatory, it has been added to required properties as well. '#sound-dai-cells' is added for reference from simple-audio-card. Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com> --- Changes in v2: * Rebased onto for-next of [1] * Add vendor prefix 'ti' to file name * Simplify 'reg' property * Removed description from 'reset-gpios' * Added reference to dai-common.yaml * Fixed node name in example There is no in-tree user for aic32x4-gpio-func, so I just converted the bindings to YAML and skipped introducing a dt-binding header for defining the constants.
