commit d2f0b53bda3193874f3905bc839888f895d1c0cf upstream.

[Why]

drm_dp_mst_topology_mgr_suspend() is added into the new reboot
sequence, which disables the UP request at the beginning.
Therefore sideband messages are blocked.

[How]

Finish MST sideband message transaction before UP request is
suppressed.

commit d33158530660bc89be3cc870a2152e4e9a76cac7 upstream.

Based on a similar patch from Rafael for radeon.

When using ATPX to control dGPU power, the state is not retained
across suspend and resume cycles by default.  This can probably
be loosened for Hybrid Graphics (_PR3) laptops where I think the
state is properly retained.

<content type='text'>
commit 2f10d823739680d2477ce34437e8a08a53117f40 upstream.

Add missing break statement in order to prevent the code from falling
through to the default case.

The resoning for this is that pclk_vol_table is an automatic variable.
So, it makes no sense to update it just before falling through to the
default case and return -EINVAL.

This bug was found thanks to the ongoing efforts to enabling
-Wimplicit-fallthrough.

[why]
Some dongle doesn't have a valid extended dongle caps,
but we still set the extended dongle caps to be valid.
This causes validation fails for all timing.

[how]
If no dp_hdmi_max_pixel_clk is provided,
don't use extended dongle caps.

[ Upstream commit 12750d1647f118496f1da727146f255f5e44d500 ]

[Why]
YCbCr420 packing format uses two chanels for luma, and 1
channel for both chroma component. Our previous implementation
did not account for this and results in every other pixel having
very high luma value, showing greyish color instead of black.

YCbCr444 = &lt;Y1, Cb1, Cr1&gt;; &lt;Y2, Cb2, Cr2&gt; .....
YCbCr420 = &lt;Y1, Y2,  Cb1&gt;; &lt;Y3, Y4,  Cr1&gt; .....

[How]
Program the second channel with the black color value for luma
as well.

[WHY]
On customer board, there is one pluse (1v , &lt; 1ms) on
DDC_CLK pin when plug / unplug DP cable. Driver will read
it and config DP to HDMI/DVI dongle.

[HOW]
If there is a real dongle, DDC_CLK should be always pull high.
Try to read again to recovery this special case. Retry times = 3.
Need additional 3ms to detect DP passive dongle(3 failures)
