Current state of the driver for the ADP5588/87 only allows partial
I/O to be used as GPIO. This support was previously present as a
separate gpio driver, which was dropped with the commit
5ddc896088b0 ("gpio: gpio-adp5588: drop the driver") since the
functionality was deemed to have been merged with adp5588-keys.

This series of patches re-enables this support by introducing a new
property names "gpio-only", which allows the driver to relax the
requirement for registering a keymap and enable pure GPIO operation. 

Changelog
==========

V2: 
	-  Changed gpio_only from a local variable to a member of struct
	adp5588_kpad
	-  Removed condition from adp5588_probe() to skip adp5588_fw_parse() if 
	gpio-only specified. adp558_fw_parse() now handles and returns
	0 if gpio-only has been specified.
	-  Added a check in adp5588_fw_parse() to make sure keypad 
	properties(keypad,num-columns and keypad,num-rows) were not defined when 
	gpio-only specified

V3:
	-  Moved device_property_present() for reading "gpio-only" into 
	adp558_fw_parse()
	-  Added print statements in case of error

V4:
	- Added dt-bindings patch
