Instead of manually iterating over the dss devices in the pipeline to
find the first one that implements the .get_modes() operation, add a new
operation flag for .get_modes() and use the omap_connector_find_device()
helper function to locate the right dss device.

omap_dss_device operations expose fixed video timings through a
.get_timings() operation that return a single timing for the device. To
prepare for the move to drm_bridge, modify the API to instead add DRM
modes directly to the connector.
As this puts more burden on display devices, we also create a helper
function for panels to add a single DRM mode from the panel video
timings.

The omapdrm and omapdss drivers are architectured based on display
pipelines made of multiple components handled from sink (display) to
source (DSS output). This is incompatible with the DRM bridge and panel
APIs that handle components from source to sink.
Reconcile the omapdrm and omapdss drivers with the DRM bridge and panel
model by reversing the direction of the DSS device .enable() and
.disable() operations. This completes the move to the DRM bridge model,
with the notable exception of the DSI pipelines that will require more
work.
We also adapt the omapdss shutdown handler dss_shutdown() to shut down
all active pipelines starting from the pipeline output device instead of
the display device.
As a consequence the for_each_dss_display() macro isn't used and can be
removed, and the omapdss_device_get_next() function underlying the macro
can be simplified to search for output devices only.

The displays (connectors, panels and encoders) bail out from their
.enable() and .disable() handlers if the dss device is already enabled
or disabled. Those safety checks are not needed when the functions are
called through the omapdss_device_ops, as the .enable() and .disable()
handlers are called from the DRM atomic helpers that already guarantee
that no double enabling or disabling can occur.
However, the handlers are also called directly from the .remove()
handler. While this shouldn't be needed either as the modules can't be
removed as long as the device is in use, it's still a good practice to
disable the device explicitly. There is currently a safety check in
.remove() in some drivers but not all of them.
Remove the safety checks from the .enable() and .disable() handlers, and
add missing ones in the .remove() handler.

The displays (connectors, panels and encoders) return an error from
their .enable() handler when the dss device is not connected. They also
disconnect the dss device explicitly from their .remove() handler if it
is still connected.
Those safety checks are not needed:
- The .enable() handler is called from code paths that access the dss
devices chain from the display device, which is set to NULL when the
device isn't connected.
- The .remove() handler can only be called when unloading the module as
the driver has the suppress_bind_attrs attribute set, and a reference
to the module is taken when constructing the dss devices chain, so the
module can only be unloaded when the dss device is disconnected.
Remove the safety checks.

The internal encoders return an error from their .enable() handler when

The .enable() handler is called from code paths that access the dss

CSC which was used on earlier platforms. And we also turn

This adds a library for shmem backed GEM objects.
v8:
- export drm_gem_shmem_create_with_handle
- call mapping_set_gfp_mask to set default zone to GFP_HIGHUSER
- Add helper drm_gem_shmem_get_pages_sgt()
v7:
- Use write-combine for mmap instead. This is the more common
case. (robher)
v6:
- Fix uninitialized variable issue in an error path (anholt).
- Add a drm_gem_shmem_vm_open() to the fops to get proper refcounting
of the pages (anholt).
v5:
- Drop drm_gem_shmem_prime_mmap() (Daniel Vetter)
- drm_gem_shmem_mmap(): Subtract drm_vma_node_start() to get the real
vma->vm_pgoff
- drm_gem_shmem_fault(): Use vmf->pgoff now that vma->vm_pgoff is correct
v4:
- Drop cache modes (Thomas Hellstrom)
- Add a GEM attached vtable
v3:
- Grammar (Sam Ravnborg)
- s/drm_gem_shmem_put_pages_unlocked/drm_gem_shmem_put_pages_locked/
(Sam Ravnborg)
- Add debug output in error path (Sam Ravnborg)

Current driver sets the tile property only for DP MST connectors.
However there are some tiled displays where each SST connector
carries a single tile. So we need to attach this property object
for every connector and set it for every connector (DP SST and MST).
Plus since the tile information is obtained as a result of EDID
parsing, the best place to update tile property is where we update
edid property.
Also now we dont need to explicitly set this now for MST connectors.
This has been tested with xrandr --props and modetest and verified
that TILE property is exposed correctly.

Fixes: 222b5f0441 ("drm/sched: Refactor ring mirror list handling.")
Now that we have the reservation object in the GEM object, it's easy
to provide a helper for this common case. Noticed while reviewing
panfrost and lima drivers. This particular version came out of v3d,
which in turn was a copy from vc4.
v2: Fix kerneldoc warnings.
