* 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. |
