The i.MX8MP has an asynchronous sample rate converter which seems to be the same as what is available on the i.MX8M Nano. Signed-off-by: Adam Ford <redacted> --- V3: No Change. The dt-binding update was already accepted into the sound tree, so that patch was dropped from the series V2: No Change.diff --git a/arch/arm64/boot/dts/freescale/imx8mp.dtsi b/arch/arm64/boot/dts/freescale/imx8mp.dtsi index 83d907294fbc..3167706d81e1 100644 --- a/arch/arm64/boot/dts/freescale/imx8mp.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mp.dtsi@@ -1459,6 +1459,26 @@ sai7: sai@30c80000 { interrupts = <GIC_SPI 111 IRQ_TYPE_LEVEL_HIGH>; status = "disabled"; }; + + easrc: easrc@30c90000 { + compatible = "fsl,imx8mp-easrc", "fsl,imx8mn-easrc"; + reg = <0x30c90000 0x10000>; + interrupts = <GIC_SPI 122 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&audio_blk_ctrl IMX8MP_CLK_AUDIOMIX_ASRC_IPG>; + clock-names = "mem"; + dmas = <&sdma2 16 23 0> , <&sdma2 17 23 0>, + <&sdma2 18 23 0> , <&sdma2 19 23 0>, + <&sdma2 20 23 0> , <&sdma2 21 23 0>, + <&sdma2 22 23 0> , <&sdma2 23 23 0>; + dma-names = "ctx0_rx", "ctx0_tx", + "ctx1_rx", "ctx1_tx", + "ctx2_rx", "ctx2_tx", + "ctx3_rx", "ctx3_tx"; + firmware-name = "imx/easrc/easrc-imx8mn.bin";
Should the firmware name really be imx8mn or should it be imx8mp ? I think the later is better, you can always add a symlink for the firmware name, and you can discern mx8mn/mp firmwares on the same rootfs in case that was ever needed in the future.
