* Atmel ClassD driver under ALSA SoC architecture
|
||||
|
||||
Required properties:
|
||||
- compatible
|
||||
Should be "atmel,sama5d2-classd".
|
||||
- reg
|
||||
Should contain ClassD registers location and length.
|
||||
- interrupts
|
||||
Should contain the IRQ line for the ClassD.
|
||||
- dmas
|
||||
One DMA specifiers as described in atmel-dma.txt and dma.txt files.
|
||||
- dma-names
|
||||
Must be "tx".
|
||||
- clock-names
|
||||
Tuple listing input clock names.
|
||||
Required elements: "pclk" and "gclk".
|
||||
- clocks
|
||||
Please refer to clock-bindings.txt.
|
||||
- assigned-clocks
|
||||
Should be <&classd_gclk>.
|
||||
|
||||
Optional properties:
|
||||
- pinctrl-names, pinctrl-0
|
||||
Please refer to pinctrl-bindings.txt.
|
||||
- atmel,model
|
||||
The user-visible name of this sound complex.
|
||||
The default value is "CLASSD".
|
||||
- atmel,pwm-type
|
||||
PWM modulation type, "single" or "diff".
|
||||
The default value is "single".
|
||||
- atmel,non-overlap-time
|
||||
Set non-overlapping time, the unit is nanosecond(ns).
|
||||
There are four values,
|
||||
<5>, <10>, <15>, <20>, the default value is <10>.
|
||||
Non-overlapping will be disabled if not specified.
|
||||
