eb4fd29afd ("drm/amdgpu: bind to any 0x1002 PCI diplay class device") added
generic bindings to amdgpu so that that it binds to all display class devices
with VID 0x1002 and then rejects those in amdgpu_pci_probe.
Unfortunately it reuses a driver_data value of 0 to detect those new bindings,
which is already used to denote CHIP_TAHITI ASICs.
The driver_data value given to those new bindings was changed in
dd0761fd24ea1 ("drm/amdgpu: set CHIP_IP_DISCOVERY as the asic type by default")
to CHIP_IP_DISCOVERY (=36), but it seems that the check in amdgpu_pci_probe
was forgotten to be changed. Therefore, it still rejects Tahiti GPUs.

It's a relatively calm development cycle, but still lots of updates in
the driver side like Intel SOF. Below are some highlights:
* ALSA / ASoC core:
- A new kselftest for ALSA control API
- PCM NO_REWINDS support
- Potential race fixes around control removals
- Unify x86 SG-buffer memory allocation code
- Cleanups and race fixes for ASoC DPCM locking
* ASoC:
- Refinements and cleanups around the delay() APIs
- Wider use of dev_err_probe().
- Continuing cleanups and improvements to the SOF code
- Support for pin switches in simple-card derived cards
- Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments

* HD-audio / USB-audio:
- Fix deadlock at HD-audio codec unbinding
- Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
- Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device
* Misc:
- Fix virmidi drain behavior
Note that the merge of CS35L41 codec support is still half-baked, and
at least one ACPI change is missing. Although this won't hinder the

Even if it's probably not really useful, it can get selected
by e.g. randconfig builds, and then failing to compile is an
annoyance. Unfortunately, it's hard to fix in Kconfig, since
DRM_TTM is selected by many things that don't really depend
on any specific architecture, and just depend on PCI (which
is indeed now available in ARCH=um via simulation/emulation).
Fix this in the code instead by just ifdef'ing the relevant

For some reason this file isn't using the appropriate register
headers for DCN headers, which means that on DCN2 we're getting
the VIEWPORT_DIMENSION offset wrong.
This means that we're not correctly carving out the framebuffer
memory correctly for a framebuffer allocated by EFI and
therefore see corruption when loading amdgpu before the display
driver takes over control of the framebuffer scanout.
Fix this by checking the DCE_HWIP and picking the correct offset
accordingly.
Long-term we should expose this info from DC as GMC shouldn't
need to know about DCN registers.

Actual hardware state of CRTC is controlled by the member 'active' in
struct drm_crtc_state instead of the member 'enable', according to the
kernel doc of the member 'enable'. In fact, the drm client modeset
and atomic helpers are using the member 'active' to do the control.
Referencing the member 'enable' of new_crtc_state, the function
crtc_needs_disable() may fail to reflect if CRTC needs disable in
self refresh mode, e.g., when the framebuffer emulation will be blanked
through the client modeset helper with the next commit, the member
'enable' of new_crtc_state is still true while the member 'active' is
false, hence the relevant potential encoder and bridges won't be disabled.
So, let's check new_crtc_state->active to determine if CRTC needs disable
in self refresh mode instead of new_crtc_state->enable.

This reverts commit a896f870f8.
It causes odd flickering on my Radeon RX580 (PCI ID 1002:67df rev e7,
subsystem ID 1da2:e353).
Bisected right to this commit, and reverting it fixes things.

Purging can happen during swapping out, or directly invoked with the
madvise ioctl. In such cases this doesn't involve a ttm move, which
skips umapping the object.

To maintain compatibility with firmware older than 4.0.11.
Those firmware may have interrmittent hangs with RDCSPIPE or the PHY,

Use the new path if firmware is development or 4.0.11 or newer. Use the

[Why]
PSP will suspend and resume DMCUB. Driver should just wait for DMCUB to
finish the auto load before continuining instead of placing it into
reset, wiping its firmware state and reinitializing.
If we don't let DMCUB fully finish initializing for S0ix then some state
will be lost and screen corruption can occur due to incorrect address
translation.
[How]
Use dmub_srv callbacks to determine in DMCUB is running and wait for
auto-load to complete before continuining.
In S0ix DMCUB will be running and DAL fw so initialize will skip.
In S3 DMCUB will not be running and we will do a full hardware init.
In S3 DMCUB will be running but will not be DAL fw so we will also do

[why]
1. Current code hard codes link to PHY mapping in dc link level per asic
per revision.
This is not scalable. In long term the mapping will be obatined from
DMUB and store in dc resource.
2. Depending on DCN revision and endpoint type, the definition of
dio_output_idx dio_output_type and phy_idx are not consistent. We need
to unify the meaning of these hardware indices across different system
configuration.
[how]
1. Temporarly move the hardcoded mapping to dc_resource level, which
should have full awareness of asic specific configuration and add a TODO
comment to move the mapping to DMUB.
2. populate dio_output_idx/phy_idx for all configuration, define
usb4_enabled bit instead of dio_output_type as an external enum.

There will be a series of re-arch changes in Link Resource Management.
They are more and more muxable link resource objects and the resource is
insufficient for a one to one allocation to all links created.
Therefore a link resource sharing logic is required to determine which
link should use certain link resource.
This commit is the first one in this series that starts by defining a
link resource struct, this struct will be available to all interfaces
that need to perform link programming sequence.
In later commits, we will granduately decouple link resource objects out
of dc link. So instead of access a link resource from dc link. Current
link's resource can be accessible through pipe_ctx->link_res during
commit, or by calling dc_link_get_cur_link_res function with current
link passed in after commit.
