Subject: [v2] drm/msm/dpu: request for display color blocks based on hw catalog entry
Date: Fri, 12 Jun 2020 11:52:37 +0530 [thread overview]
Message-ID: <1591942957-18410-1-git-send-email-mkrishn@codeaurora.org> (raw)
From: Kalyan Thota <kalyan_t@codeaurora.org>
Request for color processing blocks only if they are
available in the display hw catalog and they are
sufficient in number for the selection.
Changes in v2:
- Include Fixes tag in commit message (Rob Clark)
- Adding the Tested by tag as there are no code
changes in v2
Fixes: e47616df008b ("drm/msm/dpu: add support for color processing blocks in dpu driver")
Signed-off-by: Kalyan Thota <kalyan_t@codeaurora.org>
Tested-by: John Stultz <john.stultz@linaro.org>
