+- led-flash : the LED submodule device node
+There are two led outputs available - fled1 and fled2. Each of them can
+control a separate led or they can be connected together to double
+the maximum current for a single connected led. One led is represented
+by one child node.
+- compatible : must be "maxim,max77693-flash"
+- maxim,fleds : array of current outputs in order: fled1, fled2
+ Note: both current outputs can be connected to a single led
+ Possible values:
+ 0 - the output is left disconnected,
+ 1 - a diode is connected to the output.
Is this one needed? Just ommit child note if it is not there.
+- 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,trigger : Array of flags indicating which trigger can activate given led
+ in order: fled1, fled2
+ Possible flag values (can be combined):
+ 1 - FLASH pin of the chip,
+ 2 - TORCH pin of the chip,
+ 4 - software via I2C command.
Is it good idea to have bitfields like this?
Make these required properties of the subnode?
