29 * Using the twl4030 core we address registers using a pair
30 * { module id, relative register offset }
31 * which that core then maps to the relevant
32 * { i2c slave, absolute register address }
34 * The module IDs are meaningful only to the twl4030 core code,
35 * which uses them as array indices to look up the first register
36 * address each module uses within a given i2c slave.
