1ROHM BD28623MUV Class D speaker amplifier for digital input
2
3This codec does not have any control buses such as I2C, it detect format and
4rate of I2S signal automatically. It has two signals that can be connected
5to GPIOs: reset and mute.

7Required properties:
8- compatible      : should be "rohm,bd28623"
9- #sound-dai-cells: should be 0.
10- VCCA-supply     : regulator phandle for the VCCA supply
11- VCCP1-supply    : regulator phandle for the VCCP1 supply
12- VCCP2-supply    : regulator phandle for the VCCP2 supply
13
14Optional properties:
15- reset-gpios     : GPIO specifier for the active low reset line
16- mute-gpios      : GPIO specifier for the active low mute line
