In preparation to converting several drivers to gpiod API, and to keep=0D
existing DTS working, this series adds additional quirks to locate=0D
gpio lines with legacy names.=0D
=0D
Additionally the quirk handling has been reworked (once again) to pull=0D
all simple renames (ones that do not involve change of indices or other=0D
complex manipulations) into a single quirk with a table containing=0D
transformations. This should make adding new quirks easier.=0D
When using legacy names gpiolib will emit a message to nudge users to=0D
update DTSes (when possible).=0D
=0D
Note that the last patch requires the following change from the OF tree:=0D
=0D
        88269151be67 ("of: base: make of_device_compatible_match() accept c=
onst device node")=0D
=0D
The change is also available in mainline - it has been merged in 6.1=0D
merge window.=0D
