  • 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.

  • 77e29598c   regulator: Convert i2c drivers to use .probe_new ... Browse Code »

    Use the new .probe_new for i2c drivers.
    These drivers do not use const struct i2c_device_id * argument, so convert
    them to utilise the simplified i2c driver registration.

  • f58213637   regulator: pv88060: 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.

    There is no vsel_reg/vsel_mask settings for PV88060_ID_SWx, so don't use
    pv88060_ldo_ops for PV88060_SW. The PV88060_ID_SWx is fixed voltage,
    set .fixed_uV instead of .min_uV then regulator core will automatically
    support get_voltage and list_voltage.

    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.
