1Texas Instruments TAS5086 6-channel PWM Processor2 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 the11 chip's !RESET pin. If specified, the driver will12 assert a hardware reset at probe time.13 14 - ti,charge-period: This property should contain the time in microseconds15 that closely matches the external single-ended16 split-capacitor charge period. The hardware chip17 waits for this period of time before starting the18 PWM signals. This helps reduce pops and clicks.19 20 When not specified, the hardware default of 1300ms21 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 start25 sequence, otherwise the default Low-Z scheme is used.26 27 The correct configuration depends on how the power28 stages connected to the PWM output pins work. Not all29 power stages are compatible to Mid-Z - please refer30 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 3.3V35 - dvdd-supply: Power supply for DVDD, providing 3.3V36 37Examples: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 };49
