Subject: [PATCH v4 06/11] drm/rockchip: Use dirtyfb helper
Date:   Wed,  8 May 2019 12:09:11 -0400

From: Sean Paul <seanpaul@chromium.org>

Instead of flushing all vops every time we get a dirtyfb call, use the
damage helper to kick off an atomic commit. Even though we don't use
damage clips, the helper commit will force us through the normal
psr_inhibit_get/put sequence.

Changes in v3:
- Added to the set
Changes in v4:
- None
