wm8350_register_led - Register a WM8350 LED output

Parameters

wm8350	The WM8350 device to configure.
lednum	LED device index to create.
dcdc	The DCDC to use for the LED.
isink	The ISINK to use for the LED.
pdata	Configuration for the LED.

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.
