Subject: [PATCH 2/3] arm64: dts: qcom: sa8775p: Add interconnect to PCIe SMMU
Date: Fri, 9 Jun 2023 11:11:41 +0530 [thread overview]
Message-ID: <20230609054141.18938-3-quic_ppareek@quicinc.com> (raw)
In-Reply-To: <20230609054141.18938-1-quic_ppareek@quicinc.com>
Introduce the interconnect, connecting PCIe SMMU to the memory. This
is accessed during memory mapped IO access of smmu registers, and
during page table walks.
