Hi Preston, Are you still maintaining GPIO support for the cp210x driver? I'm looking at the last set of patches from 2012 that attempted to mainline it, but it looks like it didn't get anywhere. I'd like to try again. Have you looked at CONFIG_GPIO support in the kernel? I think the biggest complaint the last time had been the creation of a new ioctl method. Using the GPIO library should probably get around that. The GPIO userspace abi isn't fantastic, but it is already accepted, so there shouldn't be any complaints there. It also makes it possible to use the GPIO lines. g. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
