Subject: [PATCH v2 0/3] Enable quad SPI mode for SPI-NAND on IPQ RDP boards
Date: Fri, 07 Aug 2026 22:05:30 +0530 [thread overview]
Message-ID: <20260807-quad_dts-v2-0-6f578d4152b7@oss.qualcomm.com> (raw)
Several Qualcomm IPQ RDP platforms support quad (x4) SPI transfers
between the QPIC SPI-NAND controller and the attached SPI-NAND device.
However, the corresponding device trees do not currently describe the
bus width capabilities of the flash device, causing transfers to fall
back to the default single-bit (x1) mode.
This series enables quad SPI operation on supported IPQ reference
design platforms by adding spi-rx-bus-width and spi-tx-bus-width
properties to the SPI-NAND device nodes.
The series updates the IPQ9574, IPQ5424 and IPQ5332 based RDPs.
