[PATCH 00/17] i3c: mipi-i3c-hci-pci: Add Runtime PM support

[Adrian Hunter]

Hi

This patch set adds Runtime PM support to mipi-i3c-hci and
mipi-i3c-hci-pci.

Notably, the master core is enhanced to optionally support
doing the RPM gets/puts needed to ensure a device is runtime
resumed for all bus operations.  That alleviates mipi-i3c-hci
from having to do it, and if the approach is accepted, would
allow other master drivers to drop their RPM gets/puts.

There are a number of small patches making various improvements
for things hit during development.  Plus a bunch of patches
preparing for the main changes which are covered in the last 3
patches.
