drm/connector: Add support for out-of-band hotplug notification (v3)
Add a new drm_connector_oob_hotplug_event() function and
oob_hotplug_event drm_connector_funcs member.
On some hardware a hotplug event notification may come from outside the
display driver / device. An example of this is some USB Type-C setups
where the hardware muxes the DisplayPort data and aux-lines but does
not pass the altmode HPD status bit to the GPU's DP HPD pin.
In cases like this the new drm_connector_oob_hotplug_event() function can
be used to report these out-of-band events.
Changes in v2:
- Make drm_connector_oob_hotplug_event() take a fwnode as argument and
have it call drm_connector_find_by_fwnode() internally. This allows
making drm_connector_find_by_fwnode() a drm-internal function and
avoids code outside the drm subsystem potentially holding on the
a drm_connector reference for a longer period.
Changes in v3:
- Drop the data argument to the drm_connector_oob_hotplug_event
function since it is not used atm. This can be re-added later when
a use for it actually arises.

The adding of the fwnode pointer allows drivers to associate a fwnode

When the new fwnode pointer points to an ACPI-companion, then the new
acpi_bus_type will cause the ACPI subsys to bind the device instantiated

return the training result properly. If link training failed,
i915 driver would not run into link train fallback function.
And no hotplug uevent would be received by user space application.

fbdev/efifb: Release PCI device's runtime PM ref during FB destroy
Atm the EFI FB platform driver gets a runtime PM reference for the
associated GFX PCI device during probing the EFI FB platform device and
releases it only when the platform device gets unbound.
When fbcon switches to the FB provided by the PCI device's driver (for
instance i915/drmfb), the EFI FB will get only unregistered without the
EFI FB platform device getting unbound, keeping the runtime PM reference
acquired during the platform device probing. This reference will prevent
the PCI driver from runtime suspending the device.
Fix this by releasing the RPM reference from the EFI FB's destroy hook,
called when the FB gets unregistered.
While at it assert that pm_runtime_get_sync() didn't fail.

UAPI Changes:
- Add I915_MMAP_OFFSET_FIXED
On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid
type. On devices without local memory, this caching mode is invalid.
As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will
be used, depending on the object placement on creation. WB will be used
when the object can only exist in system memory, WC otherwise.
Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888
- Reinstate the mmap ioctl for (already released) integrated Gen12 platforms
Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
still to sunset the IOCTL even for integrated and require using mmap_offset.
- Reject caching/set_domain IOCTLs on discrete
Expected to become immutable property of the BO
- Disallow changing context parameters after first use on Gen12 and earlier
- Require setting context parameters at creation on platforms after Gen12
Rationale (for both): Allow less dynamic changes to the context to simplify
the implementation and avoid user shooting theirselves in the foot.
- Drop I915_CONTEXT_PARAM_RINGSIZE
Userspace PR for compute-driver has not been merged
- Drop I915_CONTEXT_PARAM_NO_ZEROMAP

drm/ingenic: Use standard drm_atomic_helper_commit_tail
By making the CRTC's .vblank_enable() function return an error when it
is known that the hardware won't deliver a VBLANK, we can drop the
ingenic_drm_atomic_helper_commit_tail() function and use the standard
drm_atomic_helper_commit_tail() function instead.

drm/i915/display: Fix the 12 BPC bits for PIPE_MISC reg
Till DISPLAY12 the PIPE_MISC bits 5-7 are used to set the
Dithering BPC, with valid values of 6, 8, 10 BPC.
For ADLP+ these bits are used to set the PORT OUTPUT BPC, with valid
values of: 6, 8, 10, 12 BPC, and need to be programmed whether
dithering is enabled or not.
This patch:
-corrects the bits 5-7 for PIPE MISC register for 12 BPC.
-renames the bits and mask to have generic names for these bits for
dithering bpc and port output bpc.
v3: Added a note for MIPI DSI which uses the PIPE_MISC for readout
for pipe_bpp. (Uma Shankar)
v2: Added 'display' to the subject and fixes tag. (Uma Shankar)
