02bb1317d5 drm/tidss: Don't use drm_device->dev_private 
Upcasting using a container_of macro is more typesafe, faster and

0df3ac7657 drm/v3d: Delete v3d_dev->pdev 
We already have it in v3d_dev->drm.dev with zero additional pointer
chasing. Personally I don't like duplicated pointers like this
because:
- reviewers need to check whether the pointer is for the same or
different objects if there's multiple
- compilers have an easier time too

To avoid having to pull in some big headers I implemented the casting
function as a macro instead of a static inline. Typechecking thanks to
container_of still assured.

But also a bit a bikeshed, so feel free to ignore.

v2: More parens for v3d_to_pdev macro (checkpatch)

b0b5849e0c drm: Add devm_drm_dev_alloc macro 
Add a new macro helper to combine the usual init sequence in drivers,
consisting of a kzalloc + devm_drm_dev_init + drmm_add_final_kfree
triplet. This allows us to remove the rather unsightly
drmm_add_final_kfree from all currently merged drivers.

The kerneldoc is only added for this new function. Existing kerneldoc
and examples will be udated at the very end, since once all drivers
are converted over to devm_drm_dev_alloc we can unexport a lot of
interim functions and make the documentation for driver authors a lot
cleaner and less confusing. There will be only one true way to
initialize a drm_device at the end of this, which is going to be
devm_drm_dev_alloc.

v2:
- Actually explain what this is for in the commit message (Sam)
- Fix checkpatch issues (Sam)

d308a881a5 drm/dp_mst: Kill the second sideband tx slot, save the world 
While we support using both tx slots for sideband transmissions, it
appears that DisplayPort devices in the field didn't end up doing a very
good job of supporting it. From section 5.2.1 of the DP 2.0
specification:

  There are MST Sink/Branch devices in the field that do not handle
  interleaved message transactions.

  To facilitate message transaction handling by downstream devices, an
  MST Source device shall generate message transactions in an atomic
  manner (i.e., the MST Source device shall not concurrently interleave
  multiple message transactions). Therefore, an MST Source device shall
  clear the Message_Sequence_No value in the Sideband_MSG_Header to 0.

This might come as a bit of a surprise since the vast majority of hubs
will support using both tx slots even if they don't support interleaved
message transactions, and we've also been using both tx slots since MST
was introduced into the kernel.

However, there is one device we've had trouble getting working
consistently with MST for so long that we actually assumed it was just
broken: the infamous Dell P2415Qb. Previously this monitor would appear
to work sometimes, but in most situations would end up timing out
LINK_ADDRESS messages almost at random until you power cycled the whole
display. After reading section 5.2.1 in the DP 2.0 spec, some closer
investigation into this infamous display revealed it was only ever
timing out on sideband messages in the second TX slot.

Sure enough, avoiding the second TX slot has suddenly made this monitor
function perfectly for the first time in five years. And since they
explicitly mention this in the specification, I doubt this is the only
monitor out there with this issue. This might even explain explain the
seemingly harmless garbage sideband responses we would occasionally see
with MST hubs!

So - rewrite our sideband TX handlers to only support one TX slot. In
order to simplify our sideband handling now that we don't support
transmitting to multiple MSTBs at once, we also move all state tracking
for down replies from mstbs to the topology manager.

b430ff7ef8 drm/stm: ltdc: check number of endpoints 
Number of endpoints could exceed the fix value MAX_ENDPOINTS(2).
Instead of increase simply this value, the number of endpoint
could be read from device tree. Load sequence has been a little
rework to take care of several panel or bridge which can be
connected/disconnected or enable/disable.

30be303108 drm/bridge: panel: Return always an error pointer in drm_panel_bridge_add() 
Since commit 89958b7cd9 ("drm/bridge: panel: Infer connector type from
panel by default"), drm_panel_bridge_add() and their variants can return
NULL and an error pointer. This is fine but none of the actual users of
the API are checking for the NULL value. Instead of change all the
users, seems reasonable to return an error pointer instead. So change
the returned value for those functions when the connector type is unknown.
