2017-01-31regulator: lp8755: constify regulator_ops structureBhumika Goyal1-1/+1
Declare regulator_ops structure as const as it is only stored in the ops field of a regulator_desc structure. This field is of type const, so regulator_ops structures having this property can be made const too.

2014-07-09regulator: lp8755: Use devm_regulator_registerHimangi Saraogi1-17/+6
This patch moves data allocated using regulator_register to devm_regulator_register and does away with the calls to regulator_unregister. Also some labels are removed and a new labelerr is introduced which is less specific to context.

2013-07-30regulator: use dev_get_platdata()Jingoo Han1-1/+1
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-07-03regulator: lp8755: Provide map_voltage()Mark Brown1-0/+1
Improve performance when setting voltages by avoiding a scan through the selectors when we can simply calculate the selector we want. Signed-off-by: Mark Brown <broonie@linaro.org>
2013-05-12regulator: Remove unnecessary include of linux/delay.h from regulator driversAxel Lin1-1/+0
All the drivers that need delay for the regulator voltage output voltage to stabilize after being enabled or after being set to a new value has been converted to implement enable_time and set_voltage_time_sel callbacks. Then regulator core will take care of the necessary delay. This patch removes the unneeded include of linux/delay.h in regulator drivers.

2013-01-17regulator: lp8755: Remove enum bucksAxel Lin1-33/+17
We already have enum lp8755_bucks in lp8755.h, so it looks pointless adding enum bucks in lp8755.c. Signed-off-by: Axel Lin <axel.lin@ingics.com> Tested-by: Daniel Jeong <gshark.jeong@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-01-08regulator: lp8755: Fix mask for pchip->mphaseAxel Lin1-1/+1
According to the datasheet, it has 9 multi-phase mode from 0 to 8 and it takes 4 bits in the register. The mask for pchip->mphase should be 0x0F. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-08regulator: lp8755: Fix lp8755_regulator_init unwind codeAxel Lin1-4/+5
It's safe to pass NULL argument to regulator_unregister(), so we can remove the NULL checking before calling regulator_unregister(). However pass a ERR_PTR to regulator_unregister() is wrong, so we need to explicitly set "pchip->rdev[buck_num] = NULL" before goto err_buck. This patch also includes below cleanups: Show correct regulator id in dev_err. Remove __devexit_p.

2012-12-24regulator: lp8755: new driver for LP8755Daniel Jeong1-0/+580
This patch is for new lp8755 regulator dirver and several unsed variables were deleted and then test was done. LP8755 : The LP8755 is a high performance power management unit.It contains six step-down DC-DC converters which can can be filexibly bundled together in multiphase converters as required by application. www.ti.com Signed-off-by: Daniel Jeong <gshark.jeong@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
