A pinctrl driver is not just a gpio controller driver. If the linux driver you're talking about is in fact an FDT pinctrl driver, then you'll essentially be embracing the entire FDT world (it's an alternative to ACPI and hints and other types of metadata for describing hardware). You'll also be breaking new ground in freebsd by being the first to try to use freebsd's FDT support framework on an x86 platform. -- Ian _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
