2009-12-17regulator: keep index within bounds in da9034_get_ldo12_voltage()Roel Kluin
If selector equals ARRAY_SIZE(da9034_ldo12_data), that is one too large already. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

2009-09-22regulator: fix calculation of voltage range in da9034_set_ldo12_voltage()Roel Kluin
For val to be greater than 7 or less than 20 is logically always true.

2009-09-22regulator: replace ADTV1 register by ADTV2 in da903xHaojian Zhuang
In PXA3xx SoC family, V_CORE power doamin is supplied by BUCK1 that is controller by ADTV1 or ADTV2 register. By default, v1 and v2 has the same copy. If v1 or v2 is updated, the last value that is written to either register takes effect. It means that v1 and v2 has different copy. And the actual voltage output is determinated by last update on either register. DA9034/35 is binded with PXA3xx SoC family. While SoC is scaling OP or entering/exiting lower power mode, SoC needs to change voltage of V_CORE power doamin. In order to be efficient, POWER I2C (hardcode) mode could be enabled in SoC. In this mode, SoC will control v2 register directly. In original DA903x driver, software will only read regulator data from v1 register. But SoC controls v2 register directly. It results that v1 and v2 isn't synchronized. Wrong data will be read from v1 register. So access v2 register in da903x driver instead.

2009-06-15regulator: Move regulator drivers to subsys_initcall()Mark Brown
Regulators need to be available early in init in order to allow them to be available for consumers when requested. This is generally done by registering them at subsys_initcall() time but not all regulator drivers have done that. Convert these drivers to do so in order to mimimise future support.

2009-03-31regulator: Pass regulator init data as explict argument when registeringMark Brown
Rather than having the regulator init data read from the platform_data member of the struct device that is registered for the regulator make the init data an explict argument passed in when registering. This allows drivers to use the platform data for their own purposes if they wish. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

2008-10-30regulator: da903x regulator bug fixJonathan Cameron
Changes the device registration part of the probe function to supply the regulator device rather than its parent (the mfd device) as this caused problems when the regulator core attempted to find constraints associated with the regulators.
