regulator: pass additional of_node to regulator_register()

2011-11-23T18:47:04+00:00

With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.

regulator: Add module.h to drivers/regulator users as required

2011-10-31T23:32:15+00:00

Another group of drivers that are taking advantage of the implicit
presence of module.h -- and will break when we pull the carpet out
from under them during a cleanup.  Fix 'em now.

regulator: Report actual configured voltage to set_voltage()

2011-01-12T14:32:59+00:00

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: keep index within bounds in da9034_get_ldo12_voltage()

2009-12-17T10:27:25+00:00

If selector equals ARRAY_SIZE(da9034_ldo12_data), that is one too
large already.

regulator: fix calculation of voltage range in da9034_set_ldo12_voltage()

2009-09-22T12:32:44+00:00

For val to be greater than 7 or less than 20 is logically always true.

regulator: replace ADTV1 register by ADTV2 in da903x

2009-09-22T12:32:37+00:00

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.
