1* Microchip I2S Multi-Channel Controller 2 3Required properties: 4- compatible: Should be "microchip,sam9x60-i2smcc". 5- reg: Should be the physical base address of the controller and the 6 length of memory mapped region. 7- interrupts: Should contain the interrupt for the controller. 8- dmas: Should be one per channel name listed in the dma-names property, 9 as described in atmel-dma.txt and dma.txt files. 10- dma-names: Identifier string for each DMA request line in the dmas property. 11 Two dmas have to be defined, "tx" and "rx". 12- clocks: Must contain an entry for each entry in clock-names. 13 Please refer to clock-bindings.txt. 14- clock-names: Should be one of each entry matching the clocks phandles list: 15 - "pclk" (peripheral clock) Required. 16 - "gclk" (generated clock) Optional (1). 17 18Optional properties: 19- pinctrl-0: Should specify pin control groups used for this controller. 20- princtrl-names: Should contain only one value - "default". 21 22 23(1) : Only the peripheral clock is required. The generated clock is optional 24 and should be set mostly when Master Mode is required. 25 26Example: 27 28 i2s@f001c000 { 29 compatible = "microchip,sam9x60-i2smcc"; 30 reg = <0xf001c000 0x100>; 31 interrupts = <34 IRQ_TYPE_LEVEL_HIGH 7>; 32 dmas = <&dma0 33 (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) | 34 AT91_XDMAC_DT_PERID(36))>, 35 <&dma0 36 (AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) | 37 AT91_XDMAC_DT_PERID(37))>; 38 dma-names = "tx", "rx"; 39 clocks = <&i2s_clk>, <&i2s_gclk>; 40 clock-names = "pclk", "gclk"; 41 pinctrl-names = "default"; 42 pinctrl-0 = <&pinctrl_i2s_default>; 43 }; 44
