The i.MX8M mini appears to have a similar G1 and G2 decoder but the
post-procesing isn't present, so different compatible flags are requred.
Since all the other parameters are the same with imx8mq, just add
the new compatible flags to nxp,imx8mq-vpu.yaml.

Just 'i.MX8' so we don't have to change this everytime?

Not compatible with the imx8mq variants?

No point in more examples just for a different compatible.

Are you OK with i.MX8M?  8MQ, 8MM, and 8MP all appear to have G1 and
G2 decoders.  The i.MX8 is different.

No, the structures associated with these compatible flags telling the
driver what features are available have options for the post-processor
in the 8MQ which are not present in the 8MM.

Just as G1 and G2 are different blocks, their "post-processor"
features are really different too.

The G2 core typically produces a tiled format, NV12_4L4,
and it an inline post-processor to convert that to linear NV12.

How does this work on the 8MM? What pixel format does it
produce natively?

It's hard to imagine the G2 block doesn't do linear NV12,
so I'm inclined to think it has that post-processing feature.

Thanks,
Ezequiel
