<id>29319378449035c6fc6391b31a3c2cbaf75be221</id>
<content type='text'>
[HOW &amp; Why]
There seems to be an issue with 2nd DPIA acquiring link encoder for tiled displays.
Solution is to remove check for eng_id before we get first dynamic encoder for it

<content type='text'>
On some APU systems, there is no atom context and so the
atom_context struct is null.

Add a check to the VBIOS_INFO branch of amdgpu_info_ioctl
to handle this case, returning all zeroes.

<title>drm/amd/display: Adjust the MST resume flow</title>

<id>ec5fa9fcdeca69edf7dab5ca3b2e0ceb1c08fe9a</id>
<content type='text'>
[Why]
In drm_dp_mst_topology_mgr_resume() today, it will resume the
mst branch to be ready handling mst mode and also consecutively do
the mst topology probing. Which will cause the dirver have chance
to fire hotplug event before restoring the old state. Then Userspace
will react to the hotplug event based on a wrong state.

[How]
Adjust the mst resume flow as:
1. set dpcd to resume mst branch status
2. restore source old state
3. Do mst resume topology probing

For drm_dp_mst_topology_mgr_resume(), it's better to adjust it to
pull out topology probing work into a 2nd part procedure of the mst
resume. Will have a follow up patch in drm.
