1 Freescale Synchronous Audio Interface (SAI).
3 The SAI is based on I2S module that used communicating with audio codecs,
4 which provides a synchronous audio interface that supports fullduplex
5 serial interfaces with frame synchronization such as I2S, AC97, TDM, and
10 - compatible: Compatible list, contains "fsl,vf610-sai" or "fsl,imx6sx-sai".
11 - reg: Offset and length of the register set for the device.
12 - clocks: Must contain an entry for each entry in clock-names.
13 - clock-names : Must include the "bus" for register access and "mclk1" "mclk2"
14 "mclk3" for bit clock and frame clock providing.
15 - dmas : Generic dma devicetree binding as described in
16 Documentation/devicetree/bindings/dma/dma.txt.
17 - dma-names : Two dmas have to be defined, "tx" and "rx".
18 - pinctrl-names: Must contain a "default" entry.
19 - pinctrl-NNN: One property must exist for each entry in pinctrl-names.
20 See ../pinctrl/pinctrl-bindings.txt for details of the property values.
21 - big-endian-regs: If this property is absent, the little endian mode will
22 be in use as default, or the big endian mode will be in use for all the
24 - big-endian-data: If this property is absent, the little endian mode will
25 be in use as default, or the big endian mode will be in use for all the
