Both port and ports names may be used in a panel-lvds binding port - for a single port ports - if there is more than one port in sub-nodes Fixes the following warning: advantech,idk-2121wr.example.dt.yaml: panel-lvds: 'port' is a required property advantech,idk-2121wr.yaml needs several ports, so uses a ports node. v2: - Use oneOf - makes the logic more obvious (Rob) - Added Fixes tag - Added port: true, ports:true v3: - Indent port/ports in required two spaces (Rob) Signed-off-by:

Daniel noted[1] that commit d606dc9a ("drm: kirin: Add register connect helper functions in drm init") was unnecessary and incorrect, as drm_dev_register does register connectors for us. Thus, this patch reverts the change as suggested by Daniel.

Whenever we walk along the dma-fence-chain, we prune signaled links to keep the chain nice and tidy. This leads to situations where we can prune a link and report the earlier fence as the target seqno -- violating our own consistency checks that the seqno is not more advanced than the last element in a dma-fence-chain. Report a NULL fence and success if the seqno has already been signaled. Signed-off-by:

Inside dma-fence-chain, we use a cmpxchg on an RCU-protected pointer. To avoid the sparse warning for using the RCU pointer directly, we have to cast away the __rcu annotation. However, we don't need to use void* everywhere and can stick to the dma_fence*. Signed-off-by:

Although it's not unexpected for drm_dp_check_act_status() to fail due to DPCD read failures (as the hub may have just been unplugged suddenly), timeouts are a bit more worrying as they either mean we need a longer timeout value, or we aren't setting up payload allocations properly. So, let's start printing errors on timeouts. Signed-off-by:

Currently we only poll for an ACT up to 30 times, with a busy-wait delay of 100µs between each attempt - giving us a timeout of 2900µs. While this might seem sensible, it would appear that in certain scenarios it can take dramatically longer then that for us to receive an ACT. On one of the EVGA MST hubs that I have available, I observed said hub sometimes taking longer then a second before signalling the ACT. These delays mostly seem to occur when previous sideband messages we've sent are NAKd by the hub, however it wouldn't be particularly surprising if it's possible to reproduce times like this simply by introducing branch devices with large LCTs since payload allocations have to take effect on every downstream device up to the payload's target. So, instead of just retrying 30 times we poll for the ACT for up to 3ms, and additionally use usleep_range() to avoid a very long and rude busy-wait. Note that the previous retry count of 30 appears to have been arbitrarily chosen, as I can't find any mention of a recommended timeout or retry count for ACTs in the DisplayPort 2.0 specification. This also goes for the range we were previously using for udelay(), although I suspect that was just copied from the recommended delay for link training on SST devices. Changes since v1: * Use readx_poll_timeout() instead of open-coding timeout loop - Sean Paul Changes since v2: * Increase poll interval to 200us - Sean Paul * Print status in hex when we timeout waiting for ACT - Sean Paul Signed-off-by:
