--- /dev/null
+* 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
+
+Example:
+ssc0: ssc@fffbc000 {
+ compatible = "atmel,at91rm9200-ssc";
+ reg = <0xfffbc000 0x4000>;
+ interrupts = <14 4 5>;
+};
--- /dev/null
+AK4104 S/PDIF transmitter
+
+This device supports SPI mode only.
+
+Required properties:
+
+ - compatible : "asahi-kasei,ak4104"
+
+ - reg : The chip select number on the SPI bus
+
+Example:
+
+spdif: ak4104@0 {
+ compatible = "asahi-kasei,ak4104";
+ reg = <0>;
+ spi-max-frequency = <5000000>;
+};
- reset-gpio: a GPIO spec to define which pin is connected to the chip's
!RESET pin
+ - cirrus,amuteb-eq-bmutec: When given, the Codec's AMUTEB=BMUTEC flag
+ is enabled.
