[PATCH V3 05/15] dt-bindings: power: supply: axp20x: Add input-current-limit-microamp

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Allow specifying a hard limit of the maximum input current. Some PMICs
such as the AXP717 can pull up to 3.25A, so allow a value to be
specified that clamps this in the event the hardware is not designed
for it.
