Implement TPS2543 USB charging control. It contains routine for setting each USB port as dedicated charging port or standard downstream port. To allow us controlling the current distributed to each port, we can select whether to allow 500mA or 1500mA for each port. BUG=chrome-os-partner:7476 TEST=Added USB port definition for BDS and tested GPIO output voltage level is correct for all modes. Change-Id: I19bc4b30d333aa802f868ebfc3a398b30e99ba0f
- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
