* twl6030: regulator: Configure STATE register instead of REMAPRajendra Nayak2010-03-031-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is no REMAP register on twl6030, instead there is a STATE register to drive a resource to a given state. The state register can be used to specify what state the resource should enter when its associated with a GRP. Register Bit field description is as below. The patch programmes the corresponding STATE registers for all LDO's to turn ON when assocaited with GRP_P1. STATE REG: Bit7 |Bit6 |Bit5 |Bit4 |Bit3 |Bit2 |Bit1 |Bit0 P3_GRP |P2_GRP |P1_GRP |RES |RES |RES |State1 |State0 State can be specified as below 00: OFF 01: ON 10: OFF 11: SLEEP Signed-off-by: Rajendra Nayak <rnayak@ti.com> Cc: Liam Girdwood <lrg@slimlogic.co.uk> Cc: Samuel Ortiz <sameo@linux.intel.com> Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
* twl-regulator: Fix reg_disable functionality for 4030 and 6030Juha Keski-Saari2009-12-171-2/+2

* twl-regulator: Add turnon delay to reg_enableJuha Keski-Saari2009-12-171-1/+7
| | | | | | | | | | This change implements a basic turnon delay in the regulator enable function to make it less probable that reg_enable returns before the regulator output is at target level Signed-off-by: Juha Keski-Saari <ext-juha.1.keski-saari@nokia.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
* twl-regulator: Restore REMAP configuration in regulator probeJuha Keski-Saari2009-12-171-0/+3
| | | | | | | | | | This change ensures the regulator REMAP register configuration is in a known state so state transitions will function as intended regardless of possible bootloader effects on it Signed-off-by: Juha Keski-Saari <ext-juha.1.keski-saari@nokia.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

| | | | | | | | | | This change includes regulator turnon delay values and the REMAP reset configuration to the twlreg_info struct, since they are basic attributes of every TWL regulator Signed-off-by: Juha Keski-Saari <ext-juha.1.keski-saari@nokia.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

* regulator: Add support for twl6030 regulatorsRajendra Nayak2009-12-141-21/+95
| | | | | | | | | | | | | | This patch updates the regulator driver to add support for TWL6030 PMIC specific LDO regulators. SMPS resources are not yet supported for TWL6030 and also .set_mode and .get_status for LDO's are yet to be implemented for TWL6030.

* mfd: Rename twl4030* driver files to enable re-useSantosh Shilimkar2009-12-131-0/+500
The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030 for OMAP3. The common modules like RTC, Regulator creates opportunity to re-use the most of the code from twl4030. This patch renames few common drivers twl4030* files to twl* to enable the code re-use.
