It seems like work regarding Power Delivery wasn’t finished for u-boot. Even if uclass_get_device would return device handle, there is no code, just printf
ret = uclass_get_device(UCLASS_PD, 0, &dev);
printf("ret = %d (dev => %p)\n", ret, dev);
return 0;
@Stephen is it planned to fix this anytime soon, or I should rather buy a few dumb power supplies?
