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.
