Applied, thanks

The revision of the imx-sdma IP that is in the i.MX8M series is the same is that as that in the i.MX7 series but the imx7d MODULE_FIRMWARE directive is wrapped in a condiditional which means it's not defined when built for aarch64 SOC_IMX8M platforms and hence you get the following errors when the driver loads on imx8m devices: imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2 imx-sdma 302c0000.dma-controller: external firmware not found, using ROM firmware Add the SOC_IMX8M into the check so the firmware can load on i.MX8.
