* 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. Example: classd: classd@fc048000 { compatible = "atmel,sama5d2-classd"; reg = <0xfc048000 0x100>; interrupts = <59 IRQ_TYPE_LEVEL_HIGH 7>; dmas = <&dma0 (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) | AT91_XDMAC_DT_PERID(47))>; dma-names = "tx"; clocks = <&classd_clk>, <&classd_gclk>; clock-names = "pclk", "gclk"; assigned-clocks = <&classd_gclk>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_classd_default>; atmel,model = "classd @ SAMA5D2-Xplained"; atmel,pwm-type = "diff"; atmel,non-overlap-time = <10>; };
