Subject: [PATCH 01/11] arm64: dts: qcom: sc7280: Mark some nodes as 'reserved'
Date: Wed, 30 Aug 2023 11:58:26 +0200 [thread overview]
Message-ID: <20230830-fp5-initial-v1-1-5a954519bbad@fairphone.com> (raw)
In-Reply-To: <20230830-fp5-initial-v1-0-5a954519bbad@fairphone.com>
With the standard Qualcomm TrustZone setup, components such as lpasscc,
pdc_reset and watchdog shouldn't be touched by Linux. Mark them with
the status 'reserved' and reeable them in the chrome-common dtsi.
