| * Atmel SSC driver. |
| |
| Required properties: |
| - compatible: "atmel,at91rm9200-ssc" or "atmel,at91sam9g45-ssc" |
| - atmel,at91rm9200-ssc: support pdc transfer |
| - atmel,at91sam9g45-ssc: support dma transfer |
| - reg: Should contain SSC registers location and length |
| - interrupts: Should contain SSC interrupt |
| - clock-names: tuple listing input clock names. |
| Required elements: "pclk" |
| - clocks: phandles to input clocks. |
| |
| |
| Required properties for devices compatible with "atmel,at91sam9g45-ssc": |
| - dmas: DMA specifier, consisting of a phandle to DMA controller node, |
| the memory interface and SSC DMA channel ID (for tx and rx). |
| See Documentation/devicetree/bindings/dma/atmel-dma.txt for details. |
| - dma-names: Must be "tx", "rx". |
| |
| Examples: |
| - PDC transfer: |
| ssc0: ssc@fffbc000 { |
| compatible = "atmel,at91rm9200-ssc"; |
| reg = <0xfffbc000 0x4000>; |
| interrupts = <14 4 5>; |
| clocks = <&ssc0_clk>; |
| clock-names = "pclk"; |
| }; |
| |
| - DMA transfer: |
| ssc0: ssc@f0010000 { |
| compatible = "atmel,at91sam9g45-ssc"; |
| reg = <0xf0010000 0x4000>; |
| interrupts = <28 4 5>; |
| dmas = <&dma0 1 13>, |
| <&dma0 1 14>; |
| dma-names = "tx", "rx"; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&pinctrl_ssc0_tx &pinctrl_ssc0_rx>; |
| status = "disabled"; |
| }; |
