Additionally the quirk handling has been reworked (once again) to pull all simple renames (ones that do not involve change of indices or other complex manipulations) into a single quirk with a table containing transformations. This should make adding new quirks easier. When using legacy names gpiolib will emit a message to nudge users to update DTSes (when possible). Note that the last patch requires the following change from the OF tree: 88269151be67 ("of: base: make of_device_compatible_match() accept const device node") The change is also available in mainline - it has been merged in 6.1 merge window. Thanks.
