This version is largely based on the previous v8 patch, with Chris's changes to the mixer bindings in particular from v9 to add names for the new register blocks. As discussed, the H616 LCD support patchset (which are largely device-tree now that the clock/reset binding definitions from v9 have been taken as a subset) will be sent separately with the rest of Chris' updates.

Thank you Ryan, I will just defer to you moving forward to ensure no
further confusion on this series and will help out wherever I can.
