1* Atmel ClassD driver under ALSA SoC architecture
2
3Required properties:
4- compatible
5 Should be "atmel,sama5d2-classd".
6- reg
7 Should contain ClassD registers location and length.
8- interrupts
9 Should contain the IRQ line for the ClassD.
10- dmas
11 One DMA specifiers as described in atmel-dma.txt and dma.txt files.
12- dma-names
13 Must be "tx".
14- clock-names
15 Tuple listing input clock names.
16 Required elements: "pclk" and "gclk".
17- clocks
18 Please refer to clock-bindings.txt.
19- assigned-clocks
20 Should be <&classd_gclk>.
21
22Optional properties:
23- pinctrl-names, pinctrl-0
24 Please refer to pinctrl-bindings.txt.
25- atmel,model
26 The user-visible name of this sound complex.
27 The default value is "CLASSD".
28- atmel,pwm-type
29 PWM modulation type, "single" or "diff".
30 The default value is "single".
31- atmel,non-overlap-time
32 Set non-overlapping time, the unit is nanosecond(ns).
33 There are four values,
34 <5>, <10>, <15>, <20>, the default value is <10>.
35 Non-overlapping will be disabled if not specified.
