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>.
