[PATCH 7/9] ASoC: SOF: imx: merge imx8 and imx8m drivers
From: Laurentiu Mihalcea
Date: Mon Feb 03 2025 - 12:20:28 EST
From: Laurentiu Mihalcea <laurentiu.mihalcea@xxxxxxx>
Now that the common interface for imx chip has been introduced,
there's no longer a need to have a separate platform driver for
imx8m. As such, merge the driver with the imx8 driver. Furthermore,
delete the old driver as it's no longer useful.
