2022-04-27drm/i915: Add first set of DG2 PCI IDsMatt Roper
The IDs added here are the subset reserved for 'motherboard down' designs of DG2. We have all the necessary support upstream to enable these now (although they'll continue to require force_probe until the usual requirements are met). The remaining DG2 IDs for add-in cards will come in a future patch once some additional required functionality has fully landed.

2022-04-27drm/i915/dp: Add workaround for spurious AUX timeouts/hotplugs on LTTPR linksImre Deak
To avoid AUX timeouts and subsequent spurious hotplug interrupts, make sure that the first DPCD access during detection is a read from an LTTPR register. Some ADLP DP link configuration at least with multiple LTTPRs expects the first DPCD access during the LTTPR/DPCD detection after hotplug to be a read from the LTTPR range starting with DP_LT_TUNABLE_PHY_REPEATER_FIELD_DATA_STRUCTURE_REV. The side effect of this read is to put each LTTPR into the LTTPR transparent or LTTPR non-transparent mode. The lack of the above read may leave some of the LTTPRs in non-LTTPR mode, while other LTTPRs in LTTPR transparent or LTTPR non-transparent mode (for instance LTTPRs after system suspend/resume that kept their mode from before suspend). Due to the different AUX timeouts the different modes imply, the DPCD access from a non-LTTPR range will timeout and lead to an LTTPR generated hotplug towards the source (which the LTTPR firmware uses to account for buggy TypeC adapters with a long wake-up delay). SYSCROS: 72939 v2: Keep DPCD read-out working on non-LTTPR platforms. v3: Summarize what and why the patch does at the beginning of the commit log.

2022-04-21drm/i915/gvt: convert to use vfio_register_emulated_iommu_devChristoph Hellwig
This is straightforward conversion, the intel_vgpu already has a pointer to the vfio_dev, which can be replaced with the embedded structure and we can replace all the mdev_get_drvdata() with a simple container_of().
