The compatible value should have something more specific
(e.g. "fsl,mpc8340-soc") before listing "simple-bus".

Calling this just "flash" would be more normal.

Ideally this should list the actual model of flash chip, before the
generic "cfi-flash".

No device_type here.

A less abbreviated name, like "fan-control" would be more usual here.

No device_type here either.

Or here.

Again "board-control" would be preferable.

Especially no device_type here.

This should have a compatible property.  It shouldn't really have
device_type, but I suspect that's a bug in the ipic binding, rather
than your tree per-se.

This actually is an 8349 board, yes?  Generally compatible should be
listed from most specific to least specific, so the 8349 entry should
go first.
