Hi!

+- maxim,boost-mode :
+	In boost mode the device can produce up to 1.2A of total current
+	on both outputs. The maximum current on each output is reduced
+	to 625mA then. If there are two child led nodes defined then boost
+	is enabled by default.
+	Possible values:
+		MAX77693_LED_BOOST_OFF - no boost,
+		MAX77693_LED_BOOST_ADAPTIVE - adaptive mode,
+		MAX77693_LED_BOOST_FIXED - 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.
+
+Required properties of the LED child node:
+- label : see Documentation/devicetree/bindings/leds/common.txt
+- maxim,fled_id : Identifier of the fled output the led is connected to;
I'm pretty sure this will be needed for about every chip that can drive
multiple LEDs. Shouldn't it be documented in the generic documentation?
OK.
Well... "fled_id" is not exactly suitable name. On other busses, it
would be "reg = <1>"?
