e216431b63 drm/amd/display: Add dc_ctx to link_enc_create() parameters
[Why&How]
Preparation to enable run time initialization of register offsets to add
dc_context to the link_enc_create callback. This is needed to get the
dc_ctx handle where register offset initialization routine is called.

b15cde19c3 drm/amd/display: Add i2c speed arbitration for dc_i2c and hdcp_i2c
[why]
HDCP 1.4 failed on SL8800 SW w/a test driver use.

[how]
Slow down the HW i2c speed when used by HW i2c.
This request: each acquired_i2c_engine setup the i2c speed needed
and sets the I2c engine for HDCP use at release_engine.

This covers SW using HW i2c engine and HDCP using HW i2c engine.
for dmcu using HW i2c engine, needs add similar logic in dmcu fw.

fa63ed8170 drm/amd/display: Enable fp16 also on DCE-11.0 - DCE-12. (v2)
Testing on a Polaris11 gpu with DCE-11.2 suggests that it
seems to work fine there, so optimistically enable it for
DCE-11 and later.

v2: drop DCE 11.0 hunk.  Carrizo (DCE 11.0) has a HW bug where FP16
scaling doesn't work.  The upscale and downscale factors were
intended to block those FP16 cases and reject the commit but
nobody ever added those to atomic check.  Once those are added
to atomic check, this can be re-enabled.

e5c4197090 drm/amd/display: Add plane capabilities to dc_caps
[Why]
The current dc_caps doesn't provide the information needed to
determine the count and type of each plane to be exposed to userspace.

There are three types of DRM planes that are exposed to userspace:

1. Primary planes (can be used for modesetting)
2. Overlay planes (can be blended below or above a primary plane)
3. Cursor planes (blended topmost)

We need to know the number and type of each in amdgpu_dm to expose
to userspace.

Hardware supports blending planes below, above or both ways depending
on the ASIC. Alpha support is also ASIC dependent. Some hardware has
dedicated pipes for overlays and other hardware combines the pipes.

All of this should be exposed in a way that DM can query and use.

[How]
Introduce the dc_plane_cap structure that describes the capabilities
for the hw planes.

It describes:
- the type of the plane
- whether the plane can blend with planes below it
- whether the plane can blend with planes above it
- whether the plane supports per pixel alpha blending
- supported formats on the plane (partial list for now)

Pre DCN ASICs don't have their full capabilities described for now.
They can be updated as needed in the future.

c69dffab81 drm/amd/display: fix eDP fast bootup for pre-raven asic

For fastboot, Bios will light up eDP before SW driver is loaded. SW
driver will check if eDP is lit by bios through reading the
BIOS_SCRATCH_3 register. If lit, SW driver will not power down eDP
power and phy to save time.

Definition of BIOS_SCRATCH_3 are missing for pre-raven asic. This
causes eDP fast boot to not work property. For some eDP panels, even
if dp tx sends NoVideoStream_flag =1 and dpcd 0x600=2, eDP rx may not
handle properly. This may cause a short flash on screen.

1877ccf6ee drm/amd/display: Change from aux_engine to dce_aux
[Why]
The aux_engine struct is needlessly complex and
is defined multiple times.  It contains function pointers
that each have only one version and are called only from
inside dce_aux.

[How]
Replace aux_engine with a new struct called dce_aux.
Remove all function pointers and call functions directly.
Remove unused functions

508f5fcb54 drm/amd/display: Compensate for XGMI SS downspread on dprefclk
[Why]
When XGMI is enabled, we need to adjust the dprefclk according to the
WAFL link's spread spectrum info. This is for VG20 (DCE121) only.

[How]
dce_clk_mgr already stores SS info, currently being used by audio clock.
Therefore, patch the clk_mgr's SS info with the xGMI SS info, if xGMI
is enabled. For display clock, adjust it during dce12_update_clocks()
before calling set_clock().

Since we rely on a mmhub register to reliably determine if xGMI is
enabled, the patching step needs to happen after resource_construct()
has initialized the hardware sequencer.

[why]
ddc engines were recently changed to be independently tracked
from pipe count.  the change was reflected in resource constructor
but not in destructor.  this manifests as a memory leak when
pipe harvesting is enabled, since not all constructed ddc engines
are freed

2 I2C/AUX engines are created. Within dc_link_aux_transfer, when
pin_data_en =2, refer to enengines[ddc_pin->pin_data->en] = NULL.
NULL point is referred later causing system crash.
