Yeah you bet :D I wrote a lengthy answer to patch 0. Point being: if we insist on this being modeled as "a kind of GPIO", then *BSD and Windows also has to think of it as "a kind of GPIO" meaning we put Linux implementation details into the DT bindings. At least the idea Rob had about register-bit-* bindings should be respected see for example: Documentation/devicetree/bindings/leds/register-bit-led.txt That naming is neutral, even if we end up solving it in Linux with a GPIO abstraction, it doesn't enforce that on $OTHER_OS.
