From: Peter Crosthwaite Date: Fri, 26 Sep 2014 05:20:25 +0000 (-0700) Subject: qdev: gpio: Re-implement qdev_connect_gpio QOM style X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=02757df2ad2d5dfc96482e2cdfa046f439dafc3d;p=qemu.git qdev: gpio: Re-implement qdev_connect_gpio QOM style Re-implement as a link setter. This should allow the QOM framework to keep track of ref counts properly etc. We need to add a default parent for the connecting input incase it's coming from a non-qdev source. We simply parent the IRQ to the machine in this case.
