From 6ab4aad3481903ac3743513517c290a3ebd39232 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ma=C3=ADra=20Canal?= Date: Tue, 15 Sep 2026 17:51:25 -0300 Subject: [PATCH] dt-bindings: display: bcm2835-v3d: Add an optional reset line MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The BCM2835 power management block drives a reset line for the V3D block that is independent of the graphics power domain, allowing the GPU to be reset without power-cycling the domain. Expose this reset line in the V3D binding. Keep the property optional, as devices like the Broadcom Cygnus don't have a reset line.
