Subject: Merge branch 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=74b7d6a91311766ab6c94f6be21bd423021ca95e;p=linux.git

Merge branch 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next

This pull includes the new Arm "komeda" DRM driver. It is currently hosted
in the same repo as the other "mali-dp" driver because it is the next
iteration of the IP.
