GSC is a graphics system controller, it provides
a chassis controller for graphics discrete cards.
There are two MEI interfaces in GSC: HECI1 and HECI2.
This series includes instantiation of the auxiliary devices for HECI2
and mei-gsc auxiliary device driver that binds to the auxiliary device.
In v2 the platform device was replaced by the auxiliary device.
v3 is the rebase over drm-tip to make public CI running.
Greg KH, please review and ACK the MEI patches after main merge window closure.
We are pushing all through gfx tree as the auxiliary device belongs there.

mei: gsc: setup char driver alive in spite of firmware handshake
failure
mei: gsc: retrieve the firmware version
Tomas Winkler (3):
drm/i915/gsc: add gsc as a mei auxiliary device
mei: add support for graphics system controller (gsc) devices
mei: gsc: add runtime pm handlers
