This patch adds a new driver for Virtio based GPIO devices.
This allows a guest VM running Linux to access GPIO lines provided by the host. It supports all basic operations, except interrupts for the GPIO lines.

Bartosz,
Can you please pick this up for 5.15, the specification is already merged now:
https://github.com/oasis-tcs/virtio-spec/blob/master/virtio-gpio.tex
I will follow up with the IRQ stuff separately.
Applied, thanks!
Bart
Um. didn't expect this to be applied yet, the driver is not sparse clean, kernel build bot gave some other warnings too.
