I resolved the issue. In this case it was my "wake_up" node in my Linux device tree. I removed the "wake_up" node from the Linux device tree, AND "typec_wakeup", and "magic_wol" from the Optee device tree. I didn't not look too closely in to why they...

Hi,I had a slightly different issue with sdmmc1 where it would not initialise without defining the "sleep" pins. I have had success with SPI5 on an STM32MP135 like this:&pinctrl { spi5_pins_mx: spi5-1 { pins1 { pinmux = <STM32_PINMUX('G', 10, A...

I'm no expert, but I think the DSI interface is completely separate to the LTCD system, and the ILI9340 does not support DSI. LTDC on the STM32 products is what the ILI datasheets calls the "8080" interface. In the device tree you need to set up the ...
