[PATCH v5 7/7] arm64: dts: qcom: sc7180: Add QSPI memory interconnect path
From: Viken Dadhaniya
Date: Wed Apr 29 2026 - 13:07:01 EST
Add the missing QSPI-to-memory interconnect path alongside the existing
configuration path. Without this path, the interconnect framework cannot
correctly vote for the bandwidth required by QSPI DMA data transfers.
