| Freescale rpmsg i2s interface. |
| |
| The rpmsg i2s is based on RPMSG that used communicating with M4 core, |
| which provides a synchronous audio interface that supports fullduplex |
| serial interfaces with frame synchronization such as I2S. |
| |
| Required properties: |
| |
| - compatible : Compatible list, contains "fsl,imx7ulp-rpmsg-i2s". |
| "fsl,imx8mq-rpmsg-i2s", "fsl,imx8qxp-rpmsg-i2s" |
| "fsl,imx8qm-rpmsg-i2s" |
| |
| - fsl,audioindex : This is an index indicating the audio device index in |
| the M4 side. |
| |
| Example: |
| rpmsg_i2s: rpmsg-i2s { |
| compatible = "fsl,imx7ulp-rpmsg-i2s"; |
| /* the audio device index in m4 domain */ |
| fsl,audioindex = <0> ; |
| status = "okay"; |
| }; |
