Subject: [PATCH v2 0/2] Add writeback scaling
Date: Fri, 12 Apr 2019 14:08:23 +0000 [thread overview]
Message-ID: <1555078094-6587-1-git-send-email-ben.davis@arm.com> (raw)
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.
