> For silicon revision A1, the USB instance number for USB1 is 3 and for
> USB2 it is 4. This changed for revision B0 where the USB instance number for
> USB1 is 0 and for USB2 it is 1, which is the intended instance number. Select the
> correct numbering according to the selected revision in the defconfig. The
> config for the B0 revision is IMX95 and for A1 it is IMX95_A0.

> This patch is based on the information provided by:
