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
