Hello!I've got a problem configuring USB OTG on a board based on the STM32MP157C. This is actually the Odyssey board by Seeed Studio, which is not directly supported by STLinux as far as I know. Actually we have custom hardware with the STM32MP157C S...

Great. We have devices in the field running with the "trusted" boot scheme.Can I even boot kernels built with the "optee" boot scheme with a "trusted" U-Boot?Because I cannot currently upgrade the bootloaders.As far as I understand, the other way aro...

@Rc.1 How did you manage to configure the pullup via the device tree? I have the problem that my GPIO muxings and additional settings are not that easily picked up and applied by the kernel. The only workaround I found so far involves writing a dumm...

I would also be interested in this. The only answer I found so far is writing a dummy driver existing solely, so we can declare something in the device tree and reference the pinctrl node for our GPIO. There has got to be a simpler solution.
