I just upgraded my working tree to v2019.10-rc3 + your v3 MX8MM patches. This somehow breaks things for me. The U-Boot proper hangs when calling uclass_get_device_by_name(). Removing this call makes the boot work again. Do you have any idea what could be wrong? Do I miss something? Thanks, Frieder > + if (ret < 0) { > + printf("Failed to find clock node.
