Yes, the vdpu34x decoder on rk356x socs should be supported by this driver but I don't have boards to test that unfortunately. This might also be used on future rockchip releases like the rk3576. But they all have their own adaptations. If you can test it on rk3568 based hardware, I'll happily add a compatible for it. > Cheers, > Diederik --nextPart3724567.ElGaqSPkdT Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
