[PATCH 0/3] Add Mali-G31 GPU to Amlogic Meson-S4

From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
Date: 2026-01-10 20:04:45
Also in: linux-amlogic, linux-devicetree, lkml

This series add support for the Mali-G31 GPU on Amlogic Meson-S4 SoCs.
Overall it's similar to Mali-G31 on G12A:
- both are using two reset lines
- both share the same OPP table
- both require the same power override quirk

The main difference is that Meson-S4 gained a second (bus) clock.

This series updates the bifrost dt-bindings for the GPU on the Meson-S4
SoC, wires up the quirk in the panfrost driver and shows how to wire up
the GPU in meson-s4.dtsi.

The .dtsi patch needs to go through the linux-amlogic tree. Would the
dt-bindings patch go along with it (to prevent binding validation
errors)? If so then only the panfrost patch would go through the
panfrost (drm/misc) tree.


Best regards,
Martin
