* regulator: Report actual configured voltage to set_voltage()Mark Brown2011-01-121-5/+12
| | | | | | | | | | | Change the interface used by set_voltage() to report the selected value to the regulator core in terms of a selector used by list_voltage(). This allows the regulator core to know the voltage that was chosen without having to do an explict get_voltage(), which would be much more expensive as it will generally access hardware.

* regulator: replace ADTV1 register by ADTV2 in da903xHaojian Zhuang2009-09-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* regulator: Move regulator drivers to subsys_initcall()Mark Brown2009-06-151-1/+1
| | | | | | | | | | | | 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.

* regulator: Pass regulator init data as explict argument when registeringMark Brown2009-03-311-1/+2
| | | | | | | | | | | 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>
