[WHY]
Currently made a change where disable_output is called using signal_type.
Using actual signal_type when calilng disable_output in power_down_encoders
would make DP to HDMI dongle not light up on boot. As it would have signal_type
SIGNAL_TYPE_DISPLAY_PORT.
[HOW]
Set signal_type to SIGNAL_TYPE_NONE unless it is eDP.

[Why]
For unknown reason, immediate flip with host VM translation on NV12
surface will underflow on last row of PTE.
[How]
Hack chroma viewport height to make fetch one more row of PTE.
Note that this will cause hubp underflow on all video underlay
cases, but the underflow is not user visible since it is in

[Why]
We need DMCUB on Renoir to support DMCU and PHY initialization.
The DMUB service provides a mechanism to load the DMCUB.
[How]
Include the DMUB service in amdgpu_dm.
Frontdoor loading of the DMCUB firmware needs to happen via PSP. To
pass the firmware to PSP we need to hand it off to the firmware list
in the base driver during software initialization.
Most of the DMUB service can technically be initialized at this point
in time, but we don't want to be allocating framebuffer memory for
hardware that doesn't support the DMCUB and in order to check that we
need to be able to read registers - something DM helpers aren't setup
to do in software initialization.
So everything but the service creation itself will get deferred to
hardware initialization.

When we call intel_bios_is_valid_vbt(), size may not actually be the
size of the VBT, but rather the size of the blob the VBT is contained
in. For example, when mapping the PCI oprom, size will be the entire
oprom size. We don't want to read beyond what is reported to be the
VBT. So make sure we vbt->vbt_size makes sense and use that for
the latter checks.

This reverts commit f4071997f1de016780ec6b79c63d90cd5886ee83.
These extra EHL entries won't behave as expected without a bit more work
on the kernel side so let's drop them until that kernel work has had a
chance to land. Userspace trying to use these new entries won't get the
advantage of the new functionality these entries are meant to provide,
but at least it won't misbehave.
When we do add these back in the future, we'll probably want to
explicitly use separate tables for ICL and EHL so that userspace
software that mistakenly uses these entries (which are undefined on ICL)
sees the same behavior it sees with all the other undefined entries.

The datasheet of V3s (and various other chips) wrote
that TCON0_DCLK_DIV can be >= 1 if only dclk is used,
and must >= 6 if dclk1 or dclk2 is used. As currently
neither dclk1 nor dclk2 is used (no writes to these
bits), let's set minimal division to 1.
If this minimal division is 6, some common dot clock
frequencies can't be produced (e.g. 30MHz will not be
possible and will fallback to 25MHz), which is
obviously not an expected behaviour.

The setting of MSA is done by the DDI .pre_enable() hook. And when we are
using MST, the MSA is only set to first mst stream by calling of
DDI .pre_eanble() hook. It raies issues to non-first mst streams.
Wrong MSA or missed MSA packets might show scrambled screen or wrong
screen.
This splits a setting of MSA to MST and SST cases. And In the MST case it
will call a setting of MSA after an allocating of Virtual Channel from
MST encoder pre_enable callback.

According to internal documents I found for CMP PCHs the PCI ID 0xA3C1
belongs to a CMP-V chipset. Based on the same docs the programming of
the PCH is compatible with that of KBP. Fix up my previous wrong
assumption accordingly using the SPT programming which in turn is the
basis for KBP.
The original bug reporter verified that this is the correct PCH
identification (the only way we'll program valid DDC pin-pair values to
the GMBUS register) and the Windows team uses the same identification
(that is using the KBP programming model for this PCH).
I filed the necessary Bspec update requests (BSpec/33734).

The gem_ctx_persistence/smoketest was detecting an odd coherency issue
inside the LRC context image; that the address of the ring buffer did
not match our associated struct intel_ring. As we set the address into
the context image when we pin the ring buffer into place before the
context is active, that leaves the question of where did it get
overwritten. Either the HW context save occurred after our pin which
would imply that our idle barriers are broken, or we overwrote the
context image ourselves. It is only in reset_active() where we dabble
inside the context image outside of a serialised path from schedule-out;
but we could equally perform the operation inside schedule-in which is
then fully serialised with the context pin -- and remains serialised by
the engine pulse with kill_context(). (The only downside, aside from
doing more work inside the engine->active.lock, was the plan to merge
all the reset paths into doing their context scrubbing on schedule-out
needs more thought.)

Since CNP it's possible for rawclk to have two different values, 19.2
and 24 MHz. If the value indicated by SFUSE_STRAP register is different
from the power on default for PCH_RAWCLK_FREQ, we'll end up having a
mismatch between the rawclk hardware and software states after
suspend/resume. On previous platforms this used to work by accident,
because the power on defaults worked just fine.
Update the rawclk also on resume. The natural place to do this would be
intel_modeset_init_hw(), however VLV/CHV need it done before
intel_power_domains_init_hw(). Thus put it there even if it feels
slightly out of place.
v2: Call intel_update_rawclck() in intel_power_domains_init_hw() for all
platforms (Ville).

drm_put_dev also calls drm_dev_unregister, so dev will be unregistered
twice.
Replace it with drm_dev_put to fix it.

live_blt is still failing on hsw, showing the hallmark of incoherency.
Since we are fairly certain that the interrupt is after the seqno is
visible, the other possibility is that the seqno is before the writes to
memory are flushed. Throw in an TLB invalidate before the breadcrumb as
we are reasonably confident that forces a CS stall.

Using the array is getting clumsy. Make things a bit more dynamic.
Remove early returns on not having child devices when the end result
after "iterating" the empty list would be the same.
v3:
- use list_add_tail to not reverse the child device list (Ville)
v2:
- stick to previous naming of child devices (Ville)
- use kzalloc, handle failure
- initialize list head earlier to keep intel_bios_driver_remove() safe

On gen7, including Haswell, the MI_FLUSH_DW command is not synchronous
with the command streamer nor is there an option to make it so. To hide
this we add a large delay on the CS so that the breadcrumb should always
be visible before the interrupt. However, that does not seem to be
enough to ensure the memory is actually coherent with the read of the
breadcrumb. The breadcrumb update is a post-sync op... Throw in a
preliminary MI_FLUSH_DW before the breadcrumb update in the hope that
helps.

It's potentially useful information when diagnosing error/warn IRQs, so
dump it to dmesg with a drm_info_printer. Hide this extra debug dumping
behind another komeda_dev->err_verbosity bit.
Note that there's not much sense in dumping it for INFO events,
since the VSYNC event will swamp the log.
