[PATCH v3] msm:disp:dpu1: add support for display for SC7180 target
From: Kalyan Thota
Date: Wed Nov 20 2019 - 07:21:15 EST
Add display hw catalog changes for SC7180 target.
Changes in v1:
- Configure register offsets and capabilities for the
display hw blocks.
Changes in v2:
- mdss_irq data type has changed in the dependent
patch, accommodate the necessary changes.
- Add co-developed-by tags in the commit msg (Stephen Boyd).
Changes in v3:
- fix kernel checkpatch errors in v2
This patch has dependency on the below series
