From 3a29355a22c0275fe864100794fee58a73175d93 Mon Sep 17 00:00:00 2001 From: Viresh Kumar <viresh.kumar@linaro.org> Date: Thu, 19 Aug 2021 10:00:22 +0530 Subject: gpio: Add virtio-gpio driver 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>.
