Description

since for some strange reason the PCF50606 is configured to not enable fast
charging when it is powered up, u-boot needs to do this at the very beginning.

  • dependson set to 36

Actually, as per USB specification, we cannot do this 'blind'.

We can only switch into full 500mA charging mode if the USB configuration has
finished and the host has acknowledged that amount of power consomption.

It is still unclear how to distinguish the AC charger from a USB host, see

  • Status changed from new to closed
  • Resolution set to wontfix

we can't really fix this. 100mA is all we can charge before the USB device
stack is running.
