* regulator: remove locking around regulator_notifier_call_chain()Michał Mirosław2020-09-071-8/+2
| | | | | | | | | | | regulator_notifier_call_chain() doesn't need rdev lock and rdev's existence is assumed in the code anyway. Remove the locks from drivers.

* regulator: pv88080: Fix notifier mutex lock warningSteve Twiss2019-03-131-0/+4
| | | | | | | | | | | | | | | | The mutex for the regulator_dev must be controlled by the caller of the regulator_notifier_call_chain(), as described in the comment for that function. Failure to mutex lock and unlock surrounding the notifier call results in a kernel WARN_ON_ONCE() which will dump a backtrace for the regulator_notifier_call_chain() when that function call is first made. The mutex can be controlled using the regulator_lock/unlock() API.

* regulator: pv88080-regulator: constify regulator_ops structureBhumika Goyal2017-01-311-2/+2
| | | | | | | | | | | | | | | | | 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.

* regulator: pv88080: Update regulator for PV88080 BB silicon supportEric Jeong2016-09-261-29/+234
| | | | | | | | | | | | | Three files are modified, the driver, header file and the binding document. Updates for the regulator source file include and .of_match_table entry and node match checking in the probe() function for a compatible pv88080 silicon type. A new "HVBUCK" is added in source file and added regsiter definition in header file for pv88080 bb silicion. The binding documentation changes have been made to reflect these updates.
