I do not think any driver is using it in a "random" fashion. I would agree if the authors just stuck any pins into some random groups named after colors or rock bands. Obviously there is a mental model of the uses somewhere behind the code. > We really should have different entries in the > pinctrl data model for these different concepts (real HW groups, and > logical/virtual/SW groups) since they're entirely different things with > different semantics. That's what the tongue-in-cheek patch tried to convey, in some kind of humorous manner. I was just trying to lighten up the discussion a bit. > Perhaps it's simplest if I just step out of pinctrl and let it exist as > it is. No not at all. Your work on defining and reviewing the pinctrl drivers and DT bindings is much appreciated. However all comittee work tend to lead to a few compromises. I don't think this one compromise is especially hard to live with.
