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. 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 drivers/gpu/drm/i915/Kconfig | 1 + drivers/gpu/drm/i915/Makefile | 3 + drivers/gpu/drm/i915/gt/intel_gsc.c | 200 +++++++++++++++++ drivers/gpu/drm/i915/gt/intel_gsc.h | 37 ++++ drivers/gpu/drm/i915/gt/intel_gt.c | 3 + drivers/gpu/drm/i915/gt/intel_gt.h | 5 + drivers/gpu/drm/i915/gt/intel_gt_irq.c | 13 ++ drivers/gpu/drm/i915/gt/intel_gt_types.h | 2 + drivers/gpu/drm/i915/i915_drv.h | 8 + drivers/gpu/drm/i915/i915_pci.c | 3 +- drivers/gpu/drm/i915/i915_reg.h | 3 + drivers/gpu/drm/i915/intel_device_info.h | 2 + drivers/misc/mei/Kconfig | 14 ++ drivers/misc/mei/Makefile | 3 + drivers/misc/mei/bus-fixup.c | 25 +++ drivers/misc/mei/gsc-me.c | 271 +++++++++++++++++++++++ drivers/misc/mei/hw-me.c | 29 ++- drivers/misc/mei/hw-me.h | 2 + include/linux/mei_aux.h | 19 ++ 19 files changed, 640 insertions(+), 3 deletions(-) create mode 100644 drivers/gpu/drm/i915/gt/intel_gsc.c create mode 100644 drivers/gpu/drm/i915/gt/intel_gsc.h create mode 100644 drivers/misc/mei/gsc-me.c create mode 100644 include/linux/mei_aux.h
