> This patch adds led-flash support to Maxim max77693 chipset.
> A device can be exposed to user space through LED subsystem
> sysfs interface or through V4L2 subdevice when the support
> for V4L2 Flash sub-devices is enabled. Device supports up to
> two leds which can work in flash and torch mode. Leds can
> be triggered externally or by software.
