[PATCH 0/5] Add driver for GSC controller

[Alexander Usyskin]

GSC is a graphics system controller, based on CSE, it provides
a chassis controller for graphics discrete cards, as well as it
supports media protection (HDCP 2.2) on selected devices.

There are two MEI interfaces in GSC: HECI1, the one that provides media
protection and HECI2 the one that provides firmware interface.

This series includes instantiation of the platform devices for HECIs
and mei-gsc platform device driver that binds to the platform device.

Greg KH, please review and ACK the MEI patches.
We are pushing all through gfx tree as the platform 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 platform device
  mei: add gsc driver
  mei: gsc: add runtime pm handlers
