In preparation to converting several drivers to gpiod API, and to keep existing DTS working, this series adds additional quirks to locate gpio lines with legacy names. 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.
