[PATCH v2 4/6] arm64: dts: qcom: sdm660: Remove FastRPC compute CB9 entry

From: Abhinav Parihar

Date: Fri Oct 23 2026 - 05:06:40 EST


Remove the compute-cb@9 nodes from sdm660 device tree to
prevent clients from selecting a secure context bank for normal FastRPC
workloads.

Secure use case support is not currently implemented upstream.
