8b3026a74f drm/omapdrm: drop fb_debug_enter/leave 
This is a no-op on atomic drivers because with atomic it's simply too
complicated to get all the locking and workers and nonblocking
synchronization correct, from essentially an NMI context. Well, too
complicated = impossible. Also, omapdrm never implemented the
mode_set_base_atomic hook, so I kinda wonder why this was ever added.

Drop the hooks.

Split out to make the functional changes stick out more.

All places where DRIVER_PRIME was used have been removed in previous
patches already.

v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE.

v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE.

v4: Don't add a space in i915_drv.c (Sam)

v5: Add note that previous patches removed all the DRIVER_PRIME users
already (Emil).

v6: Fixupe ingenic (new driver) while applying.

ee8375d5dc drm/prime: Make DRIVER_PRIME a no-op 
Drivers must fill out the handle_to_fd and fd_to_handle hooks to
enable export/import prime functionality already. The additional
DRIVER_PRIME flag doesn't serve any real purpose, since the overall
flag doesn't even tell you whether import or export or maybe even both
is supported.

Ditch it.

This patch just makes it defunct, subsequent patches will remove it
from all the drivers.

Note this changes the userspace visible errno in some situations from
EOPNOTSUPP to ENOSYS. Userspace already needs to treat both as "no
prime support", so this should break anything.

v2: Improve commit message as suggested by Emil

805dc614d5 drm/prime: Update docs 
Yes this is a bit a big patch, but since it's essentially a complete
rewrite of all the prime docs I didn't see how to better split it up.

Changes:
- Consistently point to drm_gem_object_funcs as the preferred hooks,
  where applicable.

- Document all the hooks in &drm_driver that lacked kerneldoc.

- Completely new overview section, which now also includes the cleaned
  up lifetime/reference counting subchapter. I also mentioned the weak
  references in there due to the lookup caches.

- Completely rewritten helper intro section, highlight the
  import/export related functionality.

- Polish for all the functions and more cross references.

I also sprinkled a bunch of todos all over.

Most important: 0 code changes in here. The cleanup motivated by
reading and improving all this will follow later on.

v2: Actually update the prime helper docs. Plus add a few FIXMEs that
I won't address right away in subsequent cleanup patches.

v3:
- Split out the function moving. This patch is now exclusively
  documentation changes.
- Typos and nits (Sam).

v4: Polish suggestions from Noralf.

2cfb1981dd drm/komeda: Make Komeda interrupts shareable 
Komeda interrupts may be shared with other hardware blocks.
One needs to use devm_request_irq() with IRQF_SHARED to create a shared
 interrupt handler.
As a result of not using drm_irq_install() api, one needs to set
"(struct drm_device *)->irq_enabled = true/false" to enable/disable
vblank interrupts.

Changes from v1:-
1. Squashed the following two patches into one (as the second patch is a
consequence of the first one):-
   drm/komeda: Avoid using DRIVER_IRQ_SHARED
   drm/komeda: Enable/Disable vblank interrupts
2. Fixed the commit message (as pointed by Daniel Vetter)
3. Removed calls to 'drm_irq_uninstall()' as we are no longer using
drm_irq_install()
4. Removed the struct member 'komeda_kms_driver.irq_handler' as it is not
used anywhere.
