   3 Required properties:
   4
   5  - compatible:          Should contain "ti,tas5086".
   6  - reg:                 The i2c address. Should contain <0x1b>.
   7
   8 Optional properties:
   9
  10  - reset-gpio:          A GPIO spec to define which pin is connected to the
  11                         chip's !RESET pin. If specified, the driver will
  12                         assert a hardware reset at probe time.
  13
  14  - ti,charge-period:    This property should contain the time in microseconds
  15                         that closely matches the external single-ended
  16                         split-capacitor charge period. The hardware chip
  17                         waits for this period of time before starting the
  18                         PWM signals. This helps reduce pops and clicks.
  19
  20                         When not specified, the hardware default of 1300ms
  21                         is retained.

  25         i2c_bus {
  26                 tas5086@1b {
  27                         compatible = "ti,tas5086";
  28                         reg = <0x1b>;
  29                         reset-gpio = <&gpio 23 0>;
  30                         ti,charge-period = <156000>;
  31                 };
