Subject: [PATCH 0/3] arm64: dts: qcom: sa8775p: Add interconnect to SMMU
Date: Fri, 9 Jun 2023 11:11:39 +0530 [thread overview]
Message-ID: <20230609054141.18938-1-quic_ppareek@quicinc.com> (raw)
Some qcom SoCs have SMMUs, which need the interconnect bandwidth to be
This series introduce the due support for associated interconnect, and
setting of the due interconnect-bandwidth. Setting due interconnect
bandwidth is needed to avoid the issues like [1], caused by not having
due clock votes(indirectly dependent upon interconnect bandwidth).
