7f6e7186f9 drm/amd/display: Zero-out dsc init regs
[why]
Before a statically allocated PPS data structure, that did
get zeroed-out at startup, had been re-used for making packed PPS
SDP. With S3 fix, using a non-initialized PPS data structure was
introduced, while wrongly assuming it'd get initialized before it's
populated. As a consequence 'vbr_enable' and perhaps some other
fields are left uninitialized when making packed PPS SDP. This can
affect 'simple_422' as well because of the way PPS SDP packing is
done (the fields are not masked first, only shifted). The behavior
will be different, depending on the content of uninitialized data.

[how]
Zero-out PPS data structure at initialization time before it's
populated

574304041b drm/amd/display: fix audio endpoint not getting disabled issue
[Why]
Disable_audio_stream gets enum option as a paramenter which will decide
if we free acquired resources or not. However checks for the option is
guarded by the other condition which check if audio stream is getting
diabled more than once. With both conditions combined, if we attempt to
disable audio stream twice in a row, first with keep and second with
free as an option, we will never free any resources, which will make
system think there is audio endpoint connected even after we plug out
the device

of the code that free acquired resources to outside where to keep or to
free resources is actually determined

b1f6d01c4a drm/amd/display: re structure odm to allow 4 to 1 support
Currently odm is handled using top_bottom pipe by special casing
the differing opps to differentiate from mpc combine.

Since top/bottom pipe list was made to track mpc muxing this creates
difficulties in adding a 4 pipe odm case support.

Rather than continue using mpc combine list, this change reworks odm
to use it's own linked list to keep track of odm combine pipes. This
also opens up options for using mpo with odm, if a practical use case
is ever found.

ed22eb56f2 drm/nouveau/dispnv50: Fix runtime PM ref tracking for non-blocking modesets
This is something that got noticed a while ago back when I was fixing a
large number of runtime PM related issues in nouveau, but never got
fixed:

https://patchwork.freedesktop.org/series/46815/#rev7

It's not safe to iterate the entire list of CRTCs in
nv50_disp_atomic_commit(), as we could be doing a non-blocking modeset
on one CRTC in parallel with one or more other CRTCs. Likewise, this
means it's also not safe to do so in order to track runtime PM state.
While this code is certainly wrong, so far the only issues I've seen
this cause in the wild is the occasional PM ref unbalance after an
atomic check failure + module reloading (since the PCI device will
outlive nouveau in such scenarios).

So, do this far more elegantly: grab a runtime PM ref across the modeset
and commit tail, then grab/put references for each CRTC enable/disable.
This also ends up being much simpler then the previous broken solution
we had.

Finally, since we've removed all it's users: get rid of
nouveau_drm->have_disp_power_ref.

non-blocking CRTCs on nv50, I ended up stumbling on this code when
trying to remove nouveau_drm->have_disp_power_ref, and attempted to fix
it to remove the dependency on have_disp_power_ref. However, Ilia Mirkin
pointed out that this code is actually completely useless, as pre-nv50
never had runtime PM support in the first place! Go figure.

So, since it's useless just get rid of it. Note that since the only
thing nouveau_crtc_set_config() was doing was grabbing a runtime PM ref,
calling drm_crtc_helper_set_config() then dropping the ref; we can just
remove the function entirely and just call drm_crtc_helper_set_config()
directly.

3c978f7395 drm/nouveau/gpio: check function 76 in the power check as well
Added GPIO is "Power Alert". It's uncertain if this
GPIO is set on GPU initialization or only if a change is detected by the
GPU at runtime.

This GPIO can be found on Tesla and sometimes on Fermi GPUs.

Untested, wrote according to documentation.

940794b3dd drm/nouveau/gpio: check the gpio function 16 in the power check as well
Added GPIO is "Thermal and External Power Detect". It's uncertain if this
GPIO is set on GPU initialization or only if a change is detected by the
GPU at runtime.

This GPIO can be found in Rankine and Curie and rarely on Tesla GPUs
VBIOS.

Untested, wrote according to documentation.

72251fac06 drm/nouveau/gpio: fail if gpu external power is missing
Currently, nouveau doesn't check if GPU is missing power. This
patch makes nouveau fail when this happens on latest GPUs.

It checks GPIO function 121 (External Power Emergency), which
should detect power problems on GPU initialization.

This can be disabled with nouveau.config=NvPowerChecks=1

Tested on TU104, GP106 and GF100.

v3:
*  Add config override for disabling power checks

69cbbb7b04 drm/nouveau/therm: don't attempt fan control where PMU is already managing it
There's already a condition in place which attempts to detect this, but
since we've begun to require a PMU subdev even on boards where we don't
load a custom FW, it's become inaccurate.

This will prevent unnecessarily running a periodic fan update thread on
GP100 and newer, where we don't yet override the default PMU FW.
