2009-03-31	regulator: twl4030 VAUX3 supports 3.0V	Adrian Hunter	1	-1/+4
	TWL4030 and TWL5030 support 3.0V on VAUX3. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com>
2009-03-31	twl4030-regulator: expose VPLL2	David Brownell	1	-1/+1
	Add VPLL2 to the set of twl4030-family regulators exposed for use by various drivers. It's commonly used to power the digital video outputs (e.g. LCD or DVI displays) on OMAP3 systems.

2009-03-31	twl4030-regulator: list more VAUX4 voltages	David Brownell	1	-0/+2
	The VAUX4 voltage table scrolls onto a second page in many versions of the TWL4030 family manuals. This doesn't mean we should ignore those values! Some boards use the (fully supported) 2.8V setting. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
2009-03-31	regulator: twl4030 voltage enumeration (v2)	David Brownell	1	-39/+23
	Update previously-posted twl4030 regulator driver to export supported voltages to upper layers using a new mechanism. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
2009-03-31	regulator: twl4030 regulators	David Brownell	1	-0/+511
	Support most of the LDO regulators in the twl4030 family chips. In the case of LDOs supporting MMC/SD, the voltage controls are used; but in most other cases, the regulator framework is only used to enable/disable a supplies, conserving power when a given voltage rail is not needed. The drivers/mfd/twl4030-core.c code already sets up the various regulators according to board-specific configuration, and knows that some chips don't provide the full set of voltage rails. The omitted regulators are intended to be under hardware control, such as during the hardware-mediated system powerup, powerdown, and suspend states. Unless/until software hooks are known to be safe, they won't be exported here. These regulators implement the new get_status() operation, but can't realistically implement get_mode(); the status output is effectively the result of a vote, with the relevant hardware inputs not exposed.
