Subject: [PATCH v2 1/2] arm64: dts: qcom: sm8450: Remove unneeded reserved memory nodes
Date: Sat, 11 Jul 2026 23:12:27 -0400 [thread overview]
Message-ID: <20260711-sm8450-qol-dts-v2-1-5eb2e86468c5@proton.me> (raw)
In-Reply-To: <20260711-sm8450-qol-dts-v2-0-5eb2e86468c5@proton.me>
From: Esteban Urrutia <esteuwu@proton.me>
These nodes are not present on downstream device trees and only take memory
away from the AP.
No crashes occur without these nodes, so remove them.
Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>
