   1Texas Instruments TAS5086 6-channel PWM Processor
   2
   3Required properties:
   4
   5 - compatible:          Should contain "ti,tas5086".
   6 - reg:                 The i2c address. Should contain <0x1b>.
   7
   8Optional 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.

  23Examples:
  24
  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                };
  32        };
