From 5d4e9bd79a5ab5bd4695d3becaa71da447a76a94 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 16 Jan 2013 14:53:50 +0100 Subject: mfd: twl-core: Clean up module id lookup and definitions Use enums for all module definitions: twl_module_ids for common functionality among twl4030/twl6030 twl4030_module_ids for twl4030 specific ids twl6030_module_ids for twl6030 specific ids In this way the list can be managed easier when new functionality going to be implemented.
