Subject: drm/radeon/kms: add r1xx/r2xx support for CS_KEEP_TILING_FLAGS
X-Git-Tag: upstream/snapshot3+hdmi~7918^2~112
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c9068eb296fc682513f8612168f605c169b773e4;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

drm/radeon/kms: add r1xx/r2xx support for CS_KEEP_TILING_FLAGS

Previous patch only updates r3xx+.  It's not likely
anyone will use this on r1xx/r2xx, but add it for consistency.
