This is a series of patches that implements a driver for the control
peripheral, EUD (Embedded USB Debugger). The EUD is a mini-USB hub
implemented on chip to support the USB-based debug and trace capabilities.
Apart from debug capabilities, EUD has a control peripheral. Control
Peripheral is on when EUD is on and gets signals like USB attach, pet EUD,
charge phone etc. EUD driver listens to events like USB attach or detach
and charger enable or disable and then notifies the USB driver or PMIC
driver respectively about these events via EXTCON. At regular intervals,
the EUD driver receives an interrupt to pet the driver indicating that
the software is functional.
