Subject: [PATCH 0/3] drm_panel_follower support for RMI4
Date: Fri, 11 Sep 2026 15:18:26 +0200 [thread overview]
Message-ID: <20260911-topic-rmi4_panel_follower-v1-0-c1b2cf1cdb62@oss.qualcomm.com> (raw)
RMI4 is often implemented on in-cell panels which require tight power
seqeuncing. The kernel way to approach that is the panel_follower API.
This series adds that in the RMI4 driver and wires it up on a
Snapdragon 845-based Sony Xperia XZ2, also resolving the DT warnings
stemming from the current hack.
