TWL BCI (Battery Charger Interface)
The battery charger needs to interact with the USB phy in order
to know when charging is permissible, and when there is a connection
or disconnection.
The choice of phy cannot be configured at a hardware level, so there
is no value in explicit configuration in device-tree. Rather
if there is a sibling of the BCI node which is compatible with
"ti,twl4030-usb", then that is used to determine when and how
use USB power for charging.
Required properties:
- compatible:
- "ti,twl4030-bci"

help
UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
USB 2.0 PHY interface. The ULPI specification defines a standard set
of registers that can be used to detect the vendor and product which
allows ULPI to be handled as a bus. This module is the driver for that
bus.
The ULPI interfaces (the buses) are registered by the drivers for USB
controllers which support ULPI register access and have ULPI PHY
attached to them. The ULPI PHY drivers themselves are normal PHY
drivers.
ULPI PHYs provide often functions such as ADP sensing/probing (OTG
protocol) and USB charger detection.
To compile this driver as a module, choose M here: the module will
be called ulpi.
