Not with the interface of the patch you refer to (driver-specific ioctl) at least. We have a generic gpio interface in the kernel which would have to be used. A quick glance at the datasheet also reveals that the gpio pins are only one-time configurable (default to inputs) when flashing the device ROM. So I doubt it'd be worthwhile to try to implement generic support in the mainline driver. > I have an adaptor here, I have not deeply tested it yet though, but it > basically works for me for the moment. > > Best regards, > > PS: I have seen many commits from you, I don't know who is maintaining > that file in the kernel: > https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/usb/serial/cp210x.c I'm the USB serial maintainer, so that'd be me.
