Subject: [PATCH v2 7/7] arm64: dts: qcom: sc7180: Add QSPI memory interconnect path
Date: Tue, 14 Apr 2026 22:38:25 +0530	[thread overview]
Message-ID: <20260414-spi-nor-v2-7-bcca40de4b5f@oss.qualcomm.com> (raw)
In-Reply-To: <20260414-spi-nor-v2-0-bcca40de4b5f@oss.qualcomm.com>

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.
