[PATCH 2/3] arm64: dts: qcom: ipq5424-rdp466: Enable quad SPI mode for SPI-NAND
From: Md Sadre Alam
Date: Thu Jul 16 2026 - 01:57:38 EST
Enable quad SPI transfers for the SPI-NAND device by setting both spi-rx-
bus-width and spi-tx-bus-width to 4.
Without these properties, the device uses the default single-bit bus width.
Configure the board to use 4-bit read and write transfers so the controller
and flash can operate in quad SPI mode.
