+Optional properties:
+- maxim,fleds : Array of current outputs in order: fled1, fled2.
+ Note: both current outputs can be connected to a single led
+ Possible values:
+ MAX77693_LED_FLED_UNUSED - the output is left disconnected,
+ MAX77693_LED_FLED_USED - a diode is connected to the output.
As you have a LED sub-nodes for each LED already, isn't this redundant?
Well, it seems so :)
I agreed here recklessly. This property allows to describe the
situation when one LED is connected to both outputs. Single sub-node
can describe two type of designs: one LED connected to a single
output or one LED connected to both outputs. Therefore additional
property is needed to assess what is the actual case.
