Subject: [PATCH v5 6/7] arm64: dts: qcom: kodiak: Add QSPI memory interconnect path
Date: Wed, 29 Apr 2026 22:31:41 +0530 [thread overview]
Message-ID: <20260429-spi-nor-v5-6-993016c9711e@oss.qualcomm.com> (raw)
In-Reply-To: <20260429-spi-nor-v5-0-993016c9711e@oss.qualcomm.com>
Add the missing QSPI-to-memory interconnect path alongside the existing
configuration path. Without it, the interconnect framework cannot vote for
the bandwidth required by QSPI DMA data transfers.
