-* 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".
-
-Optional properties:
- - atmel,clk-from-rk-pin: bool property.
- - When SSC works in slave mode, according to the hardware design, the
- clock can get from TK pin, and also can get from RK pin. So, add
- this parameter to choose where the clock from.
- - By default the clock is from TK pin, if the clock from RK pin, this
- property is needed.
- - #sound-dai-cells: Should contain <0>.
- - This property makes the SSC into an automatically registered DAI.
-
-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>;
-};
