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>
2013-07-15regulator: lp872x: fix a build waring and coding stylesMilo Kim1-4/+5
Fix a warning below. drivers/regulator/lp872x.c:910:33: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] And checkpatch warnings are fixed. WARNING: space prohibited before semicolon Signed-off-by: Milo Kim <milo.kim@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-05-20regulator: lp872x: support the device tree featureKim, Milo1-2/+114
This patch enables the DT structure of the LP8720 and LP8725 device. The LP872x platform data is generated when the device tree is configured. Even if the platform data is NULL, it is no issue at all because the driver is configured with the default mode.

2013-04-25regulator: lp872x: Use regulator_map_voltage_ascendAxel Lin1-0/+3
All regulators have ascendant voltage list in this driver. Use regulator_map_voltage_ascend for them. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-12-10regulator: lp872x: Kill _rdev_to_offset() functionAxel Lin1-29/+7
There is only one user calling _rdev_to_offset() function. Remove _rdev_to_offset() makes the code simpler. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-09-06regulator: lp872x: remove unnecessary functionKim, Milo1-28/+0
The lp872x_check_dvs_validity() is used for checking DVS platform data. If the DVS platform data is not defined, return as error code. Now, this is unnecessary because the default DVS mode is set in this case. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-09-06regulator: lp872x: fix NULL pointer access problemKim, Milo1-4/+4
The lp872x_set_dvs() is used for changing the DVS pin state. This function works only when the DVS platform data is defined. So don't assume that DVS data is always valid. In case the platform data is not defined, the DVS data is set to NULL for skipping the DVS pin control. DVS selection and GPIO pin number are used for the LP872x DVS pin control. For better readability, DVS selection argument is added in lp872x_set_dvs(). Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-09-06regulator: lp872x: initialize the DVS modeKim, Milo1-2/+3
The platform specific configuration(general_config) is optional. However, the DVS settings should be configured explicitly while loading the driver. This patch enables configuring the default DVS mode even though the platform data is not defined.

2012-09-06regulator: lp872x: set the default DVS modeKim, Milo1-1/+14
The lp872x driver has the DVS platform data which select the register address of the BUCK voltage. This patch enables updating the default DVS mode when the DVS platform data is not defined.

2012-07-16regulator: lp872x: Simplify implementation of lp872x_find_regulator_init_data()Axel Lin1-21/+7
Pass regulator id rahter than the index to lp872x_find_regulator_init_data(), then the code can be simpler. We can also get max_regulators by lp->num_regulators.

2012-06-20regulator: lp872x: Return -EINVAL if pdata is NULLAxel Lin1-5/+5
Return -EINVAL if pdata is NULL, otherwise we have NULL dereference bug. This patch also moves the code checking pdata earlier in lp872x_probe. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
