    Subject[PATCH v5 0/3] input: pwm-beeper: add feature to set volume level
    Date
    Make the driver accept switching volume levels via sysfs.
    This can be helpful if the beep/bell sound intensity needs
    to be adapted to the environment of the device.

    The number of volume levels available and their values can
    be specified via device tree (similar to pwm-backlight).

    The volume adjustment is done by changing the duty cycle of
    the pwm signal.

    Changes in v5:
    - fix renaming of max_volume_level to max_volume
    - remove needless variable declaration
