Hi Linus, This is the big GPIO pull-request for this merge window. We've got two new drivers, new features for existing ones (like edge detection support in gpio-ich) and a lot of minor tweaks and improvements all over the place (but not in the core gpiolib code this time). We also have much appreciated documentation fixes and extensions. The details are in the signed tag. You'll notice that we have a bunch of configfs commits in our tree not acked by the configfs maintainers. These commits implement the concept of committable items in configfs - something that was well defined in the documentation for years but has remained unimplemented. Despite the first submission of these patches back in November 2020[1] and repeated pings & resending, configfs maintainers have remained unresponsive. After reviewing these on the GPIO mailing list, we decided to pick them up ourselves and send them your way together with the first user: the new GPIO simulator. Which brings us to one of the new drivers which is a new testing module based on configfs & sysfs (as opposed to the old one using module parameters and debugfs) which allows to dynamically create simulated chips from user-space. It's meant to eventually completely replace gpio-mockup. The other new driver is the one supporting the Otto GPIO controller from Realtek. Other than configfs changes, there's nothing really controversial in there. Please pull!
