2020-09-07regulator: remove locking around regulator_notifier_call_chain()Michał Mirosław1-4/+0
regulator_notifier_call_chain() doesn't need rdev lock and rdev's existence is assumed in the code anyway. Remove the locks from drivers.

In kerneldoc format, data structures have to start with 'struct' else the kerneldoc tooling/parsers/validators get confused.

2019-02-19regulator: stpmic1: Simplify regulators registrationPascal PAILLET-LME1-116/+52
Stop using a regulator_init callback. This leads to a more simple regulator registration code. This also permits to spuress struct stpmic1_regulator. Also rename stpmic1_regulators_matches to stpmic1_matches. Signed-off-by: pascal paillet <p.paillet@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2019-02-18regulator: stpmic1: Remove regul_id and *regmap from struct stpmic1_regulatorAxel Lin1-8/+4
At the context with *rdev available, regulator core provides rdev_get_id()/rdev_get_regmap() APIs to get regulator id and *regmap. So no need to store them in struct stpmic1_regulator. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>

The regulator_linear_range arrays and stpmic1_regulator_cfgs are only accessed by this driver and the values are never changed so make them static const. regulator_ops variables can also be const. Also clean up a few empty lines in regulator_linear_range array. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
