+ * The WM8350 supports the use of an ISINK together with a DCDC to
+ * provide a power-efficient LED driver.  This function registers the
+ * regulators and instantiates the platform device for a LED.  The
+ * operating modes for the LED regulators must be configured using
+ * wm8350_isink_set_flash(), wm8350_dcdc25_set_mode() and
+ * wm8350_dcdc_set_slot() prior to calling this function.
