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.
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
