      1Maxim MAX98504 class D mono speaker amplifier
      2
      3This device supports I2C control interface and an IRQ output signal. It features
      4a PCM and PDM digital audio interface (DAI) and a differential analog input.
      5
      6Required properties:
      7
      8 - compatible : "maxim,max98504"
      9 - reg : should contain the I2C slave device address
     10 - DVDD-supply, DIOVDD-supply, PVDD-supply: power supplies for the device,
     11   as covered in ../regulator/regulator.txt
     12 - interrupts : should specify the interrupt line the device is connected to,
     13   as described in ../interrupt-controller/interrupts.txt
     14
     15Optional properties:
     16
     17 - maxim,brownout-threshold - the PVDD brownout threshold, the value must be
     18   from 0, 1...21 range, corresponding to 2.6V, 2.65V...3.65V voltage range
     19 - maxim,brownout-attenuation - the brownout attenuation to the speaker gain
     20   applied during the "attack hold" and "timed hold" phase, the value must be
     21   from 0...6 (dB) range
     22 - maxim,brownout-attack-hold-ms - the brownout attack hold phase time in ms,
     23   0...255 (VBATBROWN_ATTK_HOLD, register 0x0018)
     24 - maxim,brownout-timed-hold-ms - the brownout timed hold phase time in ms,
     25   0...255 (VBATBROWN_TIME_HOLD, register 0x0019)
     26 - maxim,brownout-release-rate-ms - the brownout release phase step time in ms,
     27   0...255 (VBATBROWN_RELEASE, register 0x001A)
     28
     29The default value when the above properties are not specified is 0,
     30the maxim,brownout-threshold property must be specified to actually enable
     31the PVDD brownout protection.

     33Example:
     34
     35 max98504@31 {
     36	compatible = "maxim,max98504";
     37	reg = <0x31>;
     38	interrupt-parent = <&gpio_bank_0>;
     39	interrupts = <2 0>;
     40
     41	DVDD-supply = <&regulator>;
     42	DIOVDD-supply = <&regulator>;
     43	PVDD-supply = <&regulator>;
     44};
