[PATCH v5 1/2] Documentation: dt-bindings: trickle charger dt binding document for ds1339

[Matti Vaittinen]

Some DS13XX devices have "trickle chargers". Introduce a device tree binding
for the resistor and diode configuration for enabling trickle charger.

+Required properties:
+- compatible: Should contain "dallas,ds1339".
+- reg: I2C address for chip
+
+Optional properties:
+- trickle-resistor-ohms : Selected resistor for trickle charger
+	Values usable for ds1339 are 250, 2000, 4000
+	Should be given if trickle charger should be enabled
+- trickle-diode-disable : Do not use internal trickle charger diode
+	Should be given if internal trickle charger diode should be disabled
+Example:
