[PATCH 5/9] arm64: dts: qcom: honor-magicbook-art-14: Mark the EC reset gpio as reserved
From: Abel Vesa
Date: Mon Aug 31 2026 - 06:40:51 EST
GPIO 65 from TLMM is used by the embedded controller as its reset line.
Reserve it to prevent Linux from requesting or reconfiguring it.
Fixes: 21b15fa5f8f4 ("arm64: dts: qcom: Add HONOR MagicBook Art 14 device tree")
