56 * The TWL4030 "Triton 2" is one of a family of a multi-function "Power
57 * Management and System Companion Device" chips originally designed for
58 * use in OMAP2 and OMAP 3 based systems. Its control interfaces use I2C,
59 * often at around 3 Mbit/sec, including for interrupt handling.
60 *
61 * This driver core provides genirq support for the interrupts emitted,
62 * by the various modules, and exports register access primitives.
63 *
64 * FIXME this driver currently requires use of the first interrupt line
65 * (and associated registers).
