Subject: [PATCH v2 3/6] arm64: dts: qcom: sc8280xp: Remove FastRPC compute CB9 entry
Date: Fri, 23 Oct 2026 14:33:05 +0530 [thread overview]
Message-ID: <20261023090308.2898683-4-abhinav.parihar@oss.qualcomm.com> (raw)
In-Reply-To: <20261023090308.2898683-1-abhinav.parihar@oss.qualcomm.com>
Remove the compute-cb@9 nodes from sc8280xp device tree to
prevent clients from selecting a secure context bank for normal FastRPC
workloads.
Secure use case support is not currently implemented upstream.
Fixes: 152d1faf1e2f ("arm64: dts: qcom: add SC8280XP platform")
