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) Acked-by:

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.

Since commit 89958b7c ("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. Suggested-by:

This reverts commit 6bb0942e. Unfortunately it would appear that the rumors we've heard of sideband message interleaving not being very well supported are true. On the Lenovo ThinkPad Thunderbolt 3 dock that I have, interleaved messages appear to just get dropped: [drm:drm_dp_mst_wait_tx_reply [drm_kms_helper]] timedout msg send 00000000571ddfd0 2 1 [dp_mst] txmsg cur_offset=2 cur_len=2 seqno=1 state=SENT path_msg=1 dst=00 [dp_mst] type=ENUM_PATH_RESOURCES contents: [dp_mst] port=2 DP descriptor for this hub: OUI 90-cc-24 dev-ID SYNA3 HW-rev 1.0 SW-rev 3.12 quirks 0x0008 It would seem like as well that this is a somewhat well known issue in the field. From section 5.4.2 of the DisplayPort 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. MST Source devices that support field policy updates by way of software should update the policy to forego the generation of interleaved message transactions. This is a bit disappointing, as features like HDCP require that we send a sideband request every ~2 seconds for each active stream. However, there isn't really anything in the specification that allows us to accurately probe for interleaved messages. If it ends up being that we -really- need this in the future, we might be able to whitelist hubs where interleaving is known to work-or maybe try some sort of heuristics. But for now, let's just play it safe and not use it. Signed-off-by:
