* regulator: pass additional of_node to regulator_register()Rajendra Nayak2011-11-231-1/+1
| | | | | | | | | | | 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 requiredPaul Gortmaker2011-11-011-0/+1
| | | | | | | | 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. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* regulator: Report actual configured voltage to set_voltage()Mark Brown2011-01-121-2/+8
| | | | | | | | | | | 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: lp3972 cleanupAxel Lin2010-10-281-7/+18
| | | | | | | | | | | | | | | | This patch includes below fixes based on Mark's comment. - Return actual error if i2c_smbus_read_byte_data() fail - Add spaces around bitwise AND operator(&) to improve readability - Add comment to explain why we need to update voltage change control register for LDO1 and LDO5 - Logging the value for diagnostics if chip reported incorrect voltage value - Add __devinit annotation for setup_regulators() - Show system control register1 value if the value is mismatched - Logging the value for diagnostics if failed to detect device Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
* Regulator: LP3972 PMIC regulator driverAxel Lin2010-10-281-0/+649
This patch adds regulator drivers for National Semiconductors LP3972 PMIC. This LP3972 PMIC controller has 3 DC/DC voltage converters and 5 low drop-out (LDO) regulators. LP3972 PMIC controller uses I2C interface. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
