You should not have CONFIG_ARCH_IMX8 in a driver. Things like that
should be handled by using a different compatible string. Also please
use the livetree API.

I asked about the use of MISC as a uclass earlier. It seems that this
device provides random numbers and perhaps hashing? It is hard to know
since I am not sure where the documentation is in this series. It
seems odd to be modelled as a MISC device. My understanding is that
there are problems with the size in SPL if a different UCLASS is used.
Is that correct? I asked about of-platdata but I didn't see any
comment on that.

This does seem to be a significant clean-up even as it is, though, so
these thoughts could be looked at after this series is applied.
