    Another example, support for which should be coming shortly, is the LED
    driver provided by the WM8350: this is a PMIC capable of producing outputs
    to drive LEDs, potentially strings of very bright LEDs. This is frequently
    used to illuminate displays but the actual function depends entirely on how
    the system has been wired up.

    The implementation is identical no matter what the LEDs are doing but the
    current out of tree drivers have two drivers for this bit of the hardware,
    one for use in the normal LED case and one for when used as a backlight,
    which is redundnant. With the driver Rodolfo has written this should no
    longer be required and the backlight trigger can be used to share the
    hardware interface code.
