[PATCH v2 0/5] drm/msm/dsi: Add DSC support to 2 panels in dual DSI mode
From: Jun Nie
Date: Thu Feb 20 2025 - 05:08:33 EST
The 2 DSI interfaces may be connected to 2 independent panels in dual-DSI
mode. Device tree binging is added and frame width for DSC is changed to
support the usage case. Support to multiple slice per packet is added for
the device setup to test the usage case.
This patch set is split from the quad-pipe patch set v1. It is also dependent
on Marijn's patch:
https://lore.kernel.org/all/20250209-drm-msm-initial-dualpipe-dsc-fixes-v2-1-9a60184fdc36@xxxxxxxxxxxxxx/
The change vs v1:
- Add device tree binding for dual panel case in handling frame width for
DSC to avoid breaking existing dual-DSI case.
- Leverage Marijn's patch to configure proper slice per interface in
dsi_update_dsc_timing().
- Polish commit comments.
- Link to v1: https://lore.kernel.org/all/20240829-sm8650-v6-11-hmd-pocf-mdss-quad-upstream-8-v1-0-bdb05b4b5a2e@xxxxxxxxxx/
