[PATCH 2/4] msm:disp:dpu1: add support for display for SC7180 target

Kalyan Thota
2019-11-25T12:00:10Z

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

Changes in v4:
- move documentation into seperate patch (Rob Herring).

This patch has dependency on the below series
