In the meantime, while you are waiting, please review other patches on the mailing lists to help with maintainer's workloads. greg k-h

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. In v4 the not needed debug prints and empty line were removed, 'select' were replaced by 'depends on' in MEI Kconfig, the new include file now listed in the MAINTATINERS file. 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.
