Subject: [PATCH 4/6] arm64: dts: qcom: glymur: Add CDSP FastRPC extended context bank
Date: Wed, 26 Aug 2026 19:15:46 +0530 [thread overview]
Message-ID: <20260826-extended-mapping-v1-4-d046c1cb9a9f@oss.qualcomm.com> (raw)
In-Reply-To: <20260826-extended-mapping-v1-0-d046c1cb9a9f@oss.qualcomm.com>
Add a fastrpc_far_region reserved-memory node and link compute-cb@12 to
it via memory-region so the driver detects it as the extended mapping
bank. Bump #address-cells and #size-cells to <2> on the fastrpc ancestor
nodes and update all compute-cb reg values to the 4-cell format to
accommodate the 64-bit iommu-addresses values.
