[PATCH v7 00/22] i3c: aspeed: Add I3C support

[Jamin Lin <jamin_lin@aspeedtech.com>]

v1:
  The initial patch series was based on work by Joe Komlodi <komlodi@google.com>.

  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 doesn't support
  multi-controller buses or HDR transfers.

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

  Next, we add 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 IBIs.
  This target is sort of like an EEPROM, and it can also send IBIs upon
  reception of a user-defined magic number.

  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.

v2:
  Jamin Lin <jamin_lin@aspeedtech.com> has taken ownership of the I3C patch
  series for upstream submission.

  Changes in this version include:

  1. Added I3C functional tests.
  2. Updated patch 4 to refine register field definitions.
  3. Updated patch 7 to correct read-only register field masks.

v3:
  1. Add Signed-off-by: Jamin Lin <jamin_lin@aspeedtech.com>
  2. Fix a typo
  3. Fix ASPEED mail server issue

v4:
  1. Add Signed-off-by: Jamin Lin <jamin_lin@aspeedtech.com> at the end of each patch.

v5:
  1. Address review feedback by updating the I3C bus and device to use the
   DEFINE_TYPES() macro instead of an explicit type registration function.
  2. Rename variables to `parent_obj` for the parent object and `parent_class`
   for the parent class to comply with QEMU QOM coding style guidelines.

v6:
  1. Add I3C maintainers and reviewer

v7:
  1.  Add I3C maintainers and reviewer
