Subject: [PATCH v2 0/5] Add driver for GSC controller

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.

Greg KH, please review and ACK the MEI patches.
We are pushing all through gfx tree as the auxiliary device belongs there.

Alexander Usyskin (2):
  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
