* NXP TFA9890
The TFA9890 is a high efficiency class-D audio amplifier with a sophisticated
SpeakerBoost protection algorithm
Required properties:
- compatible:
the string of "nxp,tfa9890"
- reg:
the i2c slave address of the IC
- gpios:
an array specifiying the two required GPIOs for operation.
- tfa_vd-supply:
specify the regulator it uses.
- tfa_max-vol-steps:
specify the max vol steps used on the platform
