-Freescale Asynchronous Sample Rate Converter (ASRC) Controller
-
-The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of a
-signal associated with an input clock into a signal associated with a different
-output clock. The driver currently works as a Front End of DPCM with other Back
-Ends Audio controller such as ESAI, SSI and SAI. It has three pairs to support
-three substreams within totally 10 channels.
-
-Required properties:
-
- - compatible : Compatible list, should contain one of the following
- compatibles:
- "fsl,imx35-asrc",
- "fsl,imx53-asrc",
- "fsl,imx8qm-asrc",
- "fsl,imx8qxp-asrc",
-
- - reg : Offset and length of the register set for the device.
-
- - interrupts : Contains the spdif interrupt.
-
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
- - dma-names : Contains "rxa", "rxb", "rxc", "txa", "txb" and "txc".
-
- - clocks : Contains an entry for each entry in clock-names.
-
- - clock-names : Contains the following entries
- "mem" Peripheral access clock to access registers.
- "ipg" Peripheral clock to driver module.
- "asrck_<0-f>" Clock sources for input and output clock.
- "spba" The spba clock is required when ASRC is placed as a
- bus slave of the Shared Peripheral Bus and when two
- or more bus masters (CPU, DMA or DSP) try to access
- it. This property is optional depending on the SoC
- design.
-
- - fsl,asrc-rate : Defines a mutual sample rate used by DPCM Back Ends.
-
- - fsl,asrc-width : Defines a mutual sample width used by DPCM Back Ends.
-
- - fsl,asrc-clk-map : Defines clock map used in driver. which is required
- by imx8qm/imx8qxp platform
- <0> - select the map for asrc0 in imx8qm/imx8qxp
- <1> - select the map for asrc1 in imx8qm/imx8qxp
-
-Optional properties:
-
- - big-endian : If this property is absent, the little endian mode
- will be in use as default. Otherwise, the big endian
- mode will be in use for all the device registers.
-
- - fsl,asrc-format : Defines a mutual sample format used by DPCM Back
- Ends, which can replace the fsl,asrc-width.
- The value is 2 (S16_LE), or 6 (S24_LE).
-
-Example:
-
-asrc: asrc@...4000 {
- compatible = "fsl,imx53-asrc";
- reg = <0x02034000 0x4000>;
- interrupts = <0 50 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clks 107>, <&clks 107>, <&clks 0>,
- <&clks 0>, <&clks 0>, <&clks 0>, <&clks 0>,
