[PATCH v4 2/7] arm64: dts: qcom: ipq5424: Add QPIC SPI NAND controller support
From: Md Sadre Alam
Date: Fri Feb 06 2026 - 05:03:12 EST
Add device tree nodes for QPIC SPI NAND flash controller support
on IPQ5424 SoC.
The IPQ5424 SoC includes a QPIC controller that supports SPI NAND flash
devices with hardware ECC capabilities and DMA support through BAM
(Bus Access Manager).
