Subject: [PATCH v1 0/2] arm64: dts + drm/panthor: require explicit GPU sram-supply
Date: Sun, 15 Feb 2026 13:01:56 +0300 [thread overview]
Message-ID: <20260215100156.135374-1-work@onurozkan.dev> (raw)
Hi all,
This series follows the discussion around panthor's SRAM regulator handling
and the DT expectations for mali GPU nodes.
Today, if sram-supply is missing in the DT file, panthor falls back to
a dummy regulator with a warning. This implicit behavior hides missing
DT wiring behind regulator core fallback.
As discussed in [1], the agreed direction is:
- Update DTs to explicitly provide sram-supply, when no separate SRAM
rail exists, use the same regulator as mali-supply.
- Make panthor to treat sram-supply as mandatory for all compatibles
except mt8196-mali (as that SoC manages SRAM outside panthor).
- First patch applies the DT updates across affected files.
- Second patch makes panthor to treat sram-supply as mandatory
except mt8196-mali.
