Subject: [PATCH] regulator: dt-bindings: rpi-panel: Mark 7" Raspberry Pi as GPIO controller
Date: Wed, 7 Jan 2026 22:36:25 +0100 [thread overview]
Message-ID: <20260107213638.505319-1-marex@nabladev.com> (raw)
Mark the Raspberry Pi 7" Display 1 ATTINY based regulator
as GPIO controller, because the hardware behaves that way
in addition to being a regulator. Add fixed gpio-cells as
well.
