Subject: [PATCH v4 2/2] dt-bindings: input: Update dtbinding for adp5588

From: Utsav Agarwal <utsav.agarwal@...log.com>

Updating dt bindings for adp5588. Following properties are now made
optional:
	- interrupts
	- keypad,num-rows
	- keypad,num-columns
	- linux,keymap
The proposed new property "gpio-only" has been added as an optional
property with an additional example.
