1Texas Instruments TAS5711/TAS5717/TAS5719/TAS5721 stereo power amplifiers
2
3The codec is controlled through an I2C interface.  It also has two other
4signals that can be wired up to GPIOs: reset (strongly recommended), and
5powerdown (optional).
6
7Required properties:
8
9- compatible: should be one of the following:
10  - "ti,tas5711",
11  - "ti,tas5717",
12  - "ti,tas5719",
13  - "ti,tas5721"
14- reg: The I2C address of the device
15- #sound-dai-cells: must be equal to 0
16
17Optional properties:
18
19- reset-gpios: GPIO specifier for the TAS571x's active low reset line
20- pdn-gpios: GPIO specifier for the TAS571x's active low powerdown line
21- clocks: clock phandle for the MCLK input
22- clock-names: should be "mclk"
23- AVDD-supply: regulator phandle for the AVDD supply (all chips)
24- DVDD-supply: regulator phandle for the DVDD supply (all chips)
25- HPVDD-supply: regulator phandle for the HPVDD supply (5717/5719)
26- PVDD_AB-supply: regulator phandle for the PVDD_AB supply (5717/5719)
27- PVDD_CD-supply: regulator phandle for the PVDD_CD supply (5717/5719)
28- PVDD_A-supply: regulator phandle for the PVDD_A supply (5711)
29- PVDD_B-supply: regulator phandle for the PVDD_B supply (5711)
30- PVDD_C-supply: regulator phandle for the PVDD_C supply (5711)
31- PVDD_D-supply: regulator phandle for the PVDD_D supply (5711)
32- DRVDD-supply: regulator phandle for the DRVDD supply (5721)
33- PVDD-supply: regulator phandle for the PVDD supply (5721)
