-Freescale Synchronous Audio Interface (SAI).
-
-The SAI is based on I2S module that used communicating with audio codecs,
-which provides a synchronous audio interface that supports fullduplex
-serial interfaces with frame synchronization such as I2S, AC97, TDM, and
-codec/DSP interfaces.
-
-Required properties:
-
- - compatible : Compatible list, contains "fsl,vf610-sai",
- "fsl,imx6sx-sai", "fsl,imx6ul-sai",
- "fsl,imx7ulp-sai", "fsl,imx8mq-sai",
- "fsl,imx8qm-sai", "fsl,imx8mm-sai",
- "fsl,imx8mn-sai", "fsl,imx8mp-sai", or
- "fsl,imx8ulp-sai".
-
- - reg : Offset and length of the register set for the device.
-
- - clocks : Must contain an entry for each entry in clock-names.
-
- - clock-names : Must include the "bus" for register access and
- "mclk1", "mclk2", "mclk3" for bit clock and frame
- clock providing.
- "pll8k", "pll11k" are optional, they are the clock
- source for root clock, one is for 8kHz series rates
- another one is for 11kHz series rates.
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
- - dma-names : Two dmas have to be defined, "tx" and "rx".
-
- - pinctrl-names : Must contain a "default" entry.
-
- - pinctrl-NNN : One property must exist for each entry in
- pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
- for details of the property values.
-
- - lsb-first : Configures whether the LSB or the MSB is transmitted
- first for the fifo data. If this property is absent,
- the MSB is transmitted first as default, or the LSB
- is transmitted first.
-
- - fsl,sai-synchronous-rx: This is a boolean property. If present, indicating
- that SAI will work in the synchronous mode (sync Tx
- with Rx) which means both the transmitter and the
- receiver will send and receive data by following
- receiver's bit clocks and frame sync clocks.
-
- - fsl,sai-asynchronous: This is a boolean property. If present, indicating
- that SAI will work in the asynchronous mode, which
- means both transmitter and receiver will send and
- receive data by following their own bit clocks and
- frame sync clocks separately.
-
- - fsl,dataline : configure the dataline. it has 3 value for each configuration
- first one means the type: I2S(1) or PDM(2)
- second one is dataline mask for 'rx'
- third one is dataline mask for 'tx'.
- for example: fsl,dataline = <1 0xff 0xff 2 0xff 0x11>;
- it means I2S type rx mask is 0xff, tx mask is 0xff, PDM type
- rx mask is 0xff, tx mask is 0x11 (dataline 1 and 4 enabled).
-
-Optional properties:
-
- - big-endian : Boolean property, required if all the SAI
- registers are big-endian rather than little-endian.
-
-Optional properties (for mx6ul):
-
- - fsl,sai-mclk-direction-output: This is a boolean property. If present,
- indicates that SAI will output the SAI MCLK clock.
-
-Note:
-- If both fsl,sai-asynchronous and fsl,sai-synchronous-rx are absent, the
- default synchronous mode (sync Rx with Tx) will be used, which means both
- transmitter and receiver will send and receive data by following clocks
- of transmitter.
-- fsl,sai-asynchronous and fsl,sai-synchronous-rx are exclusive.
-
-Example:
-sai2: sai@40031000 {
- compatible = "fsl,vf610-sai";
- reg = <0x40031000 0x1000>;
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_sai2_1>;
- clocks = <&clks VF610_CLK_PLATFORM_BUS>,
- <&clks VF610_CLK_SAI2>,
- <&clks 0>, <&clks 0>;
- clock-names = "bus", "mclk1", "mclk2", "mclk3";
- dma-names = "tx", "rx";
- dmas = <&edma0 0 VF610_EDMA_MUXID0_SAI2_TX>,
- <&edma0 0 VF610_EDMA_MUXID0_SAI2_RX>;
