2017-01-31regulator: 88pm800: constify regulator_ops structuresBhumika Goyal1-2/+2
Declare regulator_ops structures as const as they are 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.

2015-07-16regulator: 88pm800: Use regulator_nodes/of_match in the descriptorVaibhav Hiremath1-99/+44
This patch is add regulator_nodes/of_match in the regulator descriptor for using information from DT instead of specific codes. With this patch, driver gets simplified, - No need to maintain "struct of_regulator_match" table and call of_regulator_match() fn. - No need for pm800_regulator_dt_init() fn, as it was only used for of_regulator_match(). - probe() fn got simplified around regulator_config and regulator_desc initialization.

2015-07-16regulator: 88pm800: Update driver to use devm_regulator_register fnVaibhav Hiremath1-21/+6
This patch replaces standard regulator_register with devm_regulator_register() fn, as using devm_regulator_register() fn simplifies the driver return/exit path. As part of this update, patch also cleanups up all unnecessary changes which is result of this patch - - Remove _remove() fn, as devm_ variant takes care of it. - Remove pm800_regulators.regulators[] field, as it was only needed during cleanup, so we no longer need this. This also saved some amount of memory. Signed-off-by: Vaibhav Hiremath <vaibhav.hiremath@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-07-16regulator: 88pm800: Fix indentation of assignments of data structuresVaibhav Hiremath1-34/+34
This patch makes code more clean from readability point of view, make all assignments of LDO, BUCk and regulator_ops structure at the same indentation. Signed-off-by: Vaibhav Hiremath <vaibhav.hiremath@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-07-09regulator: 88pm800: fix LDO vsel_mask valueYi Zhang1-1/+1
As per datasheet, Except LDO2, all other LDO's use bit [3:0] for VOUT select. Current code uses wrong mask value of 0x1f, So this patch fixes it to use 0xf.

2013-10-11regulator: Remove max_uV from struct regulator_linear_rangeAxel Lin1-8/+6
linear ranges means each range has linear voltage settings. So we can calculate max_uV for each linear range in regulator core rather than set the max_uV field in drivers. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-08-13regulator: 88pm800: Fix checking whether num_regulator is validAxel Lin1-3/+6
The code to check whether num_regulator is valid is wrong because it should iterate all array entries rather than break from the for loop if pdata->regulators[i] is NULL. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
