2021-11-04	gpio: virtio: Add IRQ support	Viresh Kumar	1	-4/+298
	This patch adds IRQ support for the virtio GPIO driver. Note that this uses the irq_bus_lock/unlock() callbacks, since those operations over virtio may sleep.

2021-08-23	gpio: Add virtio-gpio driver	Viresh Kumar	1	-0/+375
	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. Based on the initial work posted by: "Enrico Weigelt, metux IT consult" <lkml@metux.net>.
