Subject: [PATCH v2 3/4] drm/msm/dpu: Add support for MSM8937
From: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>
Add support for MSM8937, which has MDP5 v1.14. It looks like
trimmed down version of MSM8996. Less SSPP, LM and PP blocks. No DSC,
etc.
Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>
[Remove intr_start from CTLs config, reword the commit]
