Subject: [PATCH v2 1/6] arm64: dts: qcom: lemans: Remove FastRPC compute CB9 entry
Date: Fri, 23 Oct 2026 14:33:03 +0530	[thread overview]
Message-ID: <20261023090308.2898683-2-abhinav.parihar@oss.qualcomm.com> (raw)
In-Reply-To: <20261023090308.2898683-1-abhinav.parihar@oss.qualcomm.com>

Remove the compute-cb@9 nodes from Lemans 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: f7b01bfb4b47 ("arm64: qcom: sa8775p: Add ADSP and CDSP0 fastrpc nodes")
Cc: stable@vger.kernel.org
