Hello Linus,

Here is the i3c subsystem pull request for 6.19. HDR support has finally
been added. mipi-i3c-hci has been reworked and Intel Nova Lake-S support
has been added.

There is a conflict in drivers/base/regmap/regmap-i3c.c that has been
solved properly in linux-next.

The following changes since commit 3a8660878839faadb4f1a6dd72c3179c1df56787:

Linux 6.18-rc1 (2025-10-12 13:42:36 -0700)
