27		is stopped after this period of time has passed from the start
28		of the strobe. The file is created only for the flash LED

42Description:	read/write
43		Flash strobe state. When written with 1 it triggers flash strobe
44		and when written with 0 it turns the flash off.
45
46		On read 1 means that flash is currently strobing and 0 means
47		that flash is off.

53Description:	read only
54		Space separated list of flash faults that may have occurred.
55		Flash faults are re-read after strobing the flash. Possible
56		flash faults:
57
58		* led-over-voltage - flash controller voltage to the flash LED
59			has exceeded the limit specific to the flash controller
60		* flash-timeout-exceeded - the flash strobe was still on when
61			the timeout set by the user has expired; not all flash
62			controllers may set this in all such conditions
63		* controller-over-temperature - the flash controller has
64			overheated
65		* controller-short-circuit - the short circuit protection
66			of the flash controller has been triggered
67		* led-power-supply-over-current - current in the LED power
68			supply has exceeded the limit specific to the flash
69			controller
70		* indicator-led-fault - the flash controller has detected
71			a short or open circuit condition on the indicator LED
72		* led-under-voltage - flash controller voltage to the flash
73			LED has been below the minimum limit specific to
74			the flash
75		* controller-under-voltage - the input voltage of the flash
76			controller is below the limit under which strobing the
77			flash at full current will not be possible;
78			the condition persists until this flag is no longer set
79		* led-over-temperature - the temperature of the LED has exceeded
80			its allowed upper limit
