[PATCH 00/16] i3c: aspeed: Add I3C support

Subject: [PATCH 00/16] i3c: aspeed: Add I3C support
Date: Fri, 31 Mar 2023 01:01:15 +0000

Hi all,

This series adds I3C bus support to QEMU and adds more functionality to the
Aspeed I3C controller.

This implementation is a basic implementation that introduces IBIs
(including hot-join), CCCs, and SDR data transfer. As-is, it doesnt support
multi-controller buses or HDR transfers.

First we add the I3C bus and controller model. With that added we
gradually extend the functionality of the Aspeed I3C controller so it
can do transfers.

With that added, we add 2 targets. The first target is a mock I3C
target. It's intended to be a very simple target just to verify that I3C
is working on the guest. Internally, we've used it on Linux to verify
that i3C devices can be probed and can send/receive data and send IBIs.

The second target is a remote target. The intention of this is to be
able to communicate to a target that exists outside of QEMU.

Lastly we add hotplugging support. The hotplugging doesn't do anything too
complicated, it just adds the device attempting to hotplug to the bus. It is
the device's responsibility to hot-join and go through the DAA process to
participate on the bus.

Thanks!
Joe
