Long story short: we have external dependency and the correct way to handle that is via deferred probe. As of now we are not ready to kill the legacy support but over time we should move as much as we can to DT only mode. > The first user for needs_vcc flag will be the beagleboard file.

The BeagleBoard works because the bootloader happen to enable the PWM generator which is used as a GPIO for the external HUB enable port. As soon as the bootloader stops doing this we are going to be in trouble. > > Felipe, Peter, what do you think? > > cheers, > -roger > > [1] https://lkml.org/lkml/2013/3/12/244 > -- P?ter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
