The AR934x and later (which will turn up eventually) have a new GPIO output configuration option - a real MUX rather than a "GPIO or this function." For now I'm squirreling it away in the CPU code just so it's done - I may move this to the GPIO layer later. Specifically, this is required for setting up some boards that have external receive side LNA (low noise amplifier) that gets switched on/off by the on-chip wireless MAC. If we don't add this support for those boards then we'll end up with really poor performance. (I don't yet have one of those APs, but it'll likely show up in a week.) Obtained from: Linux OpenWRT
