    leds: Add WM8350 LED driver · 0081e802

    The voltage and current regulators on the WM8350 AudioPlus PMIC can be
    used in concert to provide a power efficient LED driver.  This driver
    implements support for this within the standard LED class.
    
    Platform initialisation code should configure the LED hardware in the
    init callback provided by the WM8350 core driver.  The callback should
    use wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and
    wm8350_dcdc_set_slot() to configure the operating parameters of the
    regulators for their hardware and then then use wm8350_register_led() to
    instantiate the LED driver.
    
    This driver was originally written by Liam Girdwood, though it has been
    extensively modified since then.
