However this register space is already assigned to a different node on both MT8173 and MT8183: a clock-controller node called 'vdecsys' which is also a syscon. In order to resolve the overlapping address ranges, remove the VDEC_SYS register space from the video decoder, and add a new property to hold the phandle to the syscon, so that iospace can still be handled. Also add reg-names to be able to tell that this new register schema is used, so the driver can keep backward compatibility. Signed-off-by: Nícolas F. R. A.
