Subject: [GIT PULL] I3C changes for 6.13

Hello Linus,

Here is the i3c subsystem pull request for 6.13. We get support for
another I3C HCI controller used on AMD chips. We get more fixes for the
MIPI HCI and Silvaco drivers are they get more widespread testing.

The following changes since commit 9852d85ec9d492ebef56dc5f229416c925758edc:

  Linux 6.12-rc1 (2024-09-29 15:06:19 -0700)

are available in the Git repository at:

  i3c: Use i3cdev->desc->info instead of calling i3c_device_get_info() to avoid deadlock (2024-11-18 14:29:13 +0100)

----------------------------------------------------------------
I3C for 6.13

Core:
 - avoid possible deadlock on probe
 - ensured preferred address is used on hot-join

Drivers:
 - dw: add AMD I3C controller support
 - mipi-i3c-hci: fix SETDASA, DMA interrupts fixes
 - svc: many fixes for IBI and hotjoin
