Hi all,

v10 of this patch series adding support for the Allwinner DE33 display engine. 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.

As noted previously the new YUV support in the DE3/DE33 and RCQ/DMA shadowing in the DE33 requires more work and discussion, so that support was removed from v8 and this patch supports RGB output only.

Regards,

Ryan
