Regards, Amit From ee0a4fefed7b1867234d96db6acbf62bbd60c0c0 Mon Sep 17 00:00:00 2001 From: Amit Kucheria Date: Mon, 6 Jul 2009 16:42:37 +0300 Subject: [PATCH 1/3] MFD: TWL4030: Add support for TWL4030/5030 dynamic power switching The TWL4030/5030 family of multifunction devices allows board-specific control of the the various regulators, clock and reset lines through 'scripts' that are loaded into its memory. This allows for Dynamic Power Switching (DPS). Implement board-independent core support for DPS that is then used by board-specific code to load custom DPS scripts.
