Subject[PATCH 5.10 46/55] dmaengine: imx-sdma: Allow imx8m for imx7 FW revs
Date
From: Peter Robinson <pbrobinson@gmail.com>

commit a7cd3cf0b2e5aaacfe5e02c472bd28e98e640be7 upstream.

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.

Fixes: 1474d48bd639 ("arm64: dts: imx8mq: Add SDMA nodes")
Fixes: 941acd566b18 ("dmaengine: imx-sdma: Only check ratio on parts that support 1:1")
