I'm in a situation where a regular SPI slave device is connected to the QuadSPI pins of IMX8MQ (I know this is troublesome but it's a fact now that the PCB has already been made).
Does anyone know a way to make it work by configuring the DeviceTree and to add a Linux kernel for QuadSPI master?
linux device tree
Could you explain a bit more on how to make it work?
Yes, I'm working at the Linux kernel drivers, including the devicetree configuration. But I just don't know how to configure it.
