[Why]
Active DP dongles return no EDID when dongle
is connected, but VGA display is taken out.
Current driver behavior does not remove the
active display when this happens, and this is
a gap between dongle DTP and dongle behavior.
[How]
For active DP dongles and non-DP scenario,
disconnect sink on detection when no EDID
is read due to timeout.

During the investigation on how to add visual confirmation on top of the

introduces a set of documentation related to the RECOUT operation in
order to make it easy for developers to navigate this set of functions.

Previous patch caused crash and had been reverted. This patch
addresses the issue without regression.
[Why]
1. Driver use umachannelnumber to calculate watermarks for stutter.
In asymmetric memory config, the actual bandwidth is less than
dual-channel. The bandwidth should be the same as single-channel.
2. We found single rank dimm need additional delay time for stutter.
[How]
Get information from each DIMM. Treat memory config as a single-channel
for asymmetric memory in bandwidth calculating.
Add additional delay time for single rank dimm.

v1: Use the current and custom pstate frequencies to track the current and
user-set min/max values in manual and determinism mode. Previously, only
actual_* value was used to track the currrent and user requested value.
The value will get reassigned whenever user requests a new value with
pp_od_clk_voltage node. Hence it will show incorrect values when user
requests an invalid value or tries a partial request without committing
the values. Separating out to custom and current variable fixes such
issues.

another one is 4K 30Hz (pixelclock 297MHz).
The issue is gone after setting "power_dpm_force_performance_level" to
"high". Following the indication, we found that the issue occurs when
sclk is too low.
So resolve the issue by disabling sclk switching when there are two

If the do while loop breaks in 'if (!sg_dma_len(sgl))' in the first
iteration, err is uninitialized causing a wrong call to zap_vma_ptes().
But that is impossible to happen as a scatterlist must have at least
one valid segment.
Anyways to avoid more reports from static checkers initializing ret
here.
