Subject[PATCH v2 0/2] Add writeback scaling
Date
Add support for scaling on writeback. To do this add writeback_w and
writeback_h as writeback connector properties to specify the desired
output dimensions.
Then implement downscaling on writeback for Malidp-550 and Malidp-650
(upscaling on writeback is not supported on these devices).

v2: Use 0 as default for writeback_w,h and so update range to use 1 as
minimum.

Ben Davis (2):
drm: Add writeback_w,h properties
drm/malidp: Enable writeback scaling
