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. 36 37Example: 38classd: classd@fc048000 { 39 compatible = "atmel,sama5d2-classd"; 40 reg = <0xfc048000 0x100>; 41 interrupts = <59 IRQ_TYPE_LEVEL_HIGH 7>; 42 dmas = <&dma0 43 (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) 44 | AT91_XDMAC_DT_PERID(47))>; 45 dma-names = "tx"; 46 clocks = <&classd_clk>, <&classd_gclk>; 47 clock-names = "pclk", "gclk"; 48 assigned-clocks = <&classd_gclk>; 49 50 pinctrl-names = "default"; 51 pinctrl-0 = <&pinctrl_classd_default>; 52 atmel,model = "classd @ SAMA5D2-Xplained"; 53 atmel,pwm-type = "diff"; 54 atmel,non-overlap-time = <10>; 55}; 56
