That's not correct compatible. marvell is a vendor prefix.

Did you test the bindings before sending?

Drop description, it is obvious.

Are you sure that this is correct DTS? 32-bit numbers are usually
8-digit long. Plus size of 0x20000 is crazy huge. And the unit address
is a bit unusual. Are you sure dtc W=1 does not say about any errors in
your DTS?

Use defines for common flags.
