[PATCH v2 0/2] drm/msm/dsi: support multiple DSC slices per packet
From: Alexander Koskovich
Date: Wed Mar 18 2026 - 05:58:37 EST
This series adds support for sending multiple DSC slices in a single
DSI packet, which is required by some panels such as the JDI LPM026M648C.
The MSM DRM change was originally authored by Jonathan Marek [1], changed to
use an 'all slices in packet' flag which derives slice_per_pkt from slice_count
instead of manually specifying the number of slices per packet.
Was also split into two patches so they can go through different trees.
