  • e9c142b0d   regulator: remove locking around regulator_notifier_call_chain() ... Browse Code »

    regulator_notifier_call_chain() doesn't need rdev lock and rdev's
    existence is assumed in the code anyway. Remove the locks from drivers.

  • 1867af94c   regulator: pv88080: Fix notifier mutex lock warning ... Browse Code »

    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.

  • d4fdf5e14   regulator: pv88080-regulator: constify regulator_ops structure ... Browse Code »

    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.

  • 5ff00f6aa   regulator: pv88080: Update regulator for PV88080 BB silicon support ... Browse Code »

    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.
