But why?

I don't see how this would work.

Convince them to release more details on the CedarX hardware design
might work, indirectly aiding development of a free driver. But I would
not count on it.

Freeing a proprietary piece of software (or hardware) which has been
proprietary for many years is inherently complex process. And efficient
video decoding is a lot about software. And it's a key technology for
Allwinner. And it's a company where marketing do not understand why
arch/arm/mach-XXXX/ needs to be provided in source form.
