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", "gclk" and "aclk". 17- clocks 18 Please refer to clock-bindings.txt. 19 20Optional properties: 21- pinctrl-names, pinctrl-0 22 Please refer to pinctrl-bindings.txt. 23- atmel,model 24 The user-visible name of this sound complex. 25 The default value is "CLASSD". 26- atmel,pwm-type 27 PWM modulation type, "single" or "diff". 28 The default value is "single". 29- atmel,non-overlap-time 30 Set non-overlapping time, the unit is nanosecond(ns). 31 There are four values, 32 <5>, <10>, <15>, <20>, the default value is <10>. 33 Non-overlapping will be disabled if not specified. 34 35Example: 36classd: classd@fc048000 { 37 compatible = "atmel,sama5d2-classd"; 38 reg = <0xfc048000 0x100>; 39 interrupts = <59 IRQ_TYPE_LEVEL_HIGH 7>; 40 dmas = <&dma0 41 (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) 42 | AT91_XDMAC_DT_PERID(47))>; 43 dma-names = "tx"; 44 clocks = <&classd_clk>, <&classd_gclk>, <&audio_pll_pmc>; 45 clock-names = "pclk", "gclk", "aclk"; 46 47 pinctrl-names = "default"; 48 pinctrl-0 = <&pinctrl_classd_default>; 49 atmel,model = "classd @ SAMA5D2-Xplained"; 50 atmel,pwm-type = "diff"; 51 atmel,non-overlap-time = <10>; 52}; 53
