/*
* The TWL4030 "Triton 2" is one of a family of a multi-function "Power
* Management and System Companion Device" chips originally designed for
* use in OMAP2 and OMAP 3 based systems. Its control interfaces use I2C,
* often at around 3 Mbit/sec, including for interrupt handling.
*
* This driver core provides genirq support for the interrupts emitted,
* by the various modules, and exports register access primitives.
*
* FIXME this driver currently requires use of the first interrupt line
* (and associated registers).
