Merge tag 'drm-intel-next-2022-05-06' of git://anongit.freedesktop.org/drm/drm-intel into drm-next

drm/i915 feature pull #2 for v5.19:

Features and functionality:
- Add first set of DG2 PCI IDs for "motherboard down" designs (Matt Roper)
- Add initial RPL-P PCI IDs as ADL-P subplatform (Matt Atwood)

Refactoring and cleanups:
- Power well refactoring and cleanup (Imre)
- GVT-g refactor and mdev API cleanup (Christoph, Jason, Zhi)
- DPLL refactoring and cleanup (Ville)
- VBT panel specific data parsing cleanup (Ville)
- Use drm_mode_init() for on-stack modes (Ville)

Fixes:
- Fix PSR state pipe A/B confusion by clearing more state on disable (José)
- Fix FIFO underruns caused by not taking DRAM channel into account (Vinod)
- Fix FBC flicker on display 11+ by enabling a workaround (José)
- Fix VBT seamless DRRS min refresh rate check (Ville)
- Fix panel type assumption on bogus VBT data (Ville)
- Fix panel data parsing for VBT that misses panel data pointers block (Ville)
- Fix spurious AUX timeout/hotplug handling on LTTPR links (Imre)

Merges:
- Backmerge drm-next (Jani)
- GVT changes (Jani)

-
-Physical Device Driver Interface
---------------------------------
-
-The physical device driver interface provides the mdev_parent_ops[3] structure
-to define the APIs to manage work in the mediated core driver that is related
-to the physical device.
-
-The structures in the mdev_parent_ops structure are as follows:
-
-* dev_attr_groups: attributes of the parent device
-* mdev_attr_groups: attributes of the mediated device
-* supported_config: attributes to define supported configurations
-* device_driver: device driver to bind for mediated device instances
-
-The mdev_parent_ops also still has various functions pointers.  Theses exist
-for historical reasons only and shall not be used for new drivers.
+The mediated bus driver's probe function should create a vfio_device on top of
+the mdev_device and connect it to an appropriate implementation of
+vfio_device_ops.
 
 When a driver wants to add the GUID creation sysfs to an existing device it has
 probe'd to then it should call::
 
 	extern int  mdev_register_device(struct device *dev,
-	                                 const struct mdev_parent_ops *ops);
+	                                 struct mdev_driver *mdev_driver);
 
 This will provide the 'mdev_supported_types/XX/create' files which can then be
 used to trigger the creation of a mdev_device. The created mdev_device will be
