From 42015c133b74f2f483798d58683ac17b587f7bbb Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 3 Nov 2009 14:42:06 +0000 Subject: [PATCH 1/7] ARM: SMDK6410: Hook up regulator supplies for WM8580 DVDD is supplied by supplies derived from the PMIC, AVDD and PVDD are supplied from the main wall supply on the base board which runs at 5V. No option is currently supported for running without a PMIC card, the assumption is that the regulator API will be built out when no soft PMIC card is in use. To ease merge issues since this uses the newly added dev_name supply configuration from the regulator API (currently in -next only) the fixed voltage regulator is ifdefed out when the regulator API is not enabled.

Originally the code was using only quoted values, resulting in some fairly odd settings. The S3C6410 is also unusual in that the both the maximum and minimum voltages quoted scale as the frequency rises, rather than just the minimum voltage. Clean this up a bit by always using the specified typical settings as the minimum voltage (ignoring any specified minimum voltage) in order to avoid running near the edge of the processor capabilities. Also use the next quoted maximum voltages rather than the typical voltages where no maximum voltage is quoted, allowing operation on a greater range of systems.
