Subject: [PATCH v5 0/5] Add DSC v1.2 Support for DSI
Date: Mon, 22 May 2023 18:08:54 -0700 [thread overview]
Message-ID: <20230405-add-dsc-support-v5-0-028c10850491@quicinc.com> (raw)
This is a series of changes for DSI to enable command mode support
for DSC v1.2.
This includes:
1) Rounding up `hdisplay / 3` in dsc_timing_setup()
2) Adjusting pclk_rate to account for compression
3) Fixing incorrect uses of slice_count in DSI DSC calculations
4) Setting the DATA_COMPRESS bit when DSC is enabled
With these changes (and the dependency below), DSC v1.2 should work over
DSI in command mode.
Note: Changes that add DSC v1.2 support for video mode will be posted
with the DP support changes.
Depends-on:
- "add DSC 1.2 dpu supports" [1]
- "Introduce MSM-specific DSC helpers" [2]
- "drm/msm/dsi: use mult_frac for pclk_bpp calculation" [3]
