+Optional properties of "led-flash" node:
+- maxim,iout : Array of four intensities in microampheres of the current
+ in order: flash1, flash2, torch1, torch2.
+ Range:
+ flash - 15625 - 1000000,
+ torch - 15625 - 250000.
+- maxim,trigger : Array of flags indicating which trigger can activate given led
+ in order: flash1, flash2, torch1, torch2.
+ Possible flag values (can be combined):
+ 1 - FLASH pin of the chip,
+ 2 - TORCH pin of the chip,
+ 4 - software via I2C command.
+- maxim,trigger-type : Array of trigger types in order: flash, torch.
+ Possible trigger types:
+ 0 - Rising edge of the signal triggers the flash/torch,
+ 1 - Signal level controls duration of the flash/torch.
+- maxim,timeout : Array of timeouts in microseconds after which leds are
+ turned off in order: flash, torch.
+ Range:
+ flash: 62500 - 1000000,
+ torch: 0 (no timeout) - 15728000.
+- maxim,boost-mode : Array of the flash boost modes in order: flash1, flash2.
+ Possible values:
+ 0 - no boost,
+ 1 - adaptive mode,
+ 2 - fixed mode.
+- maxim,boost-vout : Output voltage of the boost module in millivolts.
+- maxim,vsys-min : Low input voltage level in millivolts. Flash is not fired
+ if chip estimates that system voltage could drop below this level due
+ to flash power consumption.
