1 Texas Instruments TAS5086 6-channel PWM Processor
2
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.
22
23 - ti,mid-z-channel-X: Boolean properties, X being a number from 1 to 6.
24 If given, channel X will start with the Mid-Z start
25 sequence, otherwise the default Low-Z scheme is used.
26
27 The correct configuration depends on how the power
28 stages connected to the PWM output pins work. Not all
29 power stages are compatible to Mid-Z - please refer
30 to the datasheets for more details.
31
32 Most systems should not set any of these properties.
33
34 - avdd-supply: Power supply for AVDD, providing 3.3V
35 - dvdd-supply: Power supply for DVDD, providing 3.3V

37 Examples:
38
39 i2c_bus {
40 tas5086@1b {
41 compatible = "ti,tas5086";
42 reg = <0x1b>;
43 reset-gpio = <&gpio 23 0>;
44 ti,charge-period = <156000>;
45 avdd-supply = <&vdd_3v3_reg>;
46 dvdd-supply = <&vdd_3v3_reg>;
47 };
48 };
