[PATCH 3/4] dt: bindings: lm3692x: Update binding for LED sync control

From: Dan Murphy
Date: Mon Jul 02 2018 - 14:13:07 EST


Update the binding to be able to configure the LED
sync to turn on.

The LM36922 has one output but can sync current to 2 LED
strings. The user may only use one sync so the other
syncs need to be disabled.

The LM36923 has 3 LED syncs.
