[PATCH 01/16] dt-bindings: display: bridge: renesas,dsi: Document RZ/G3L
From: Biju <hidden>
Date: 2026-07-04 09:34:43
Also in:
dri-devel, linux-renesas-soc, lkml
Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for bridge chips, open firmware and flattened device tree bindings, the rest · Maintainers:
David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Andrzej Hajda, Neil Armstrong, Robert Foss, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
From: Biju Das <biju.das.jz@bp.renesas.com>
The RZ/G3L DSI IP is similar to the RZ/G2L but has different global PHY
timings and also the PLLCLK is ungateble clock. Add the compatible
string "renesas,r9a08g046-mipi-dsi" to handle these difference for the
Renesas RZ/G3L SoC. The power to DSI region is controlled by SYSC block.
Document renesas,sysc-pwrrdy property to handle the power control.
