d2d7885f75 drm/amd/display: add seamless boot flag to stream
[Why]
If we determine the stream we are trying to commit
matches HW, we want to try to optimize.

[How]
Try to acquire the HW resources that are already enabled
and optimize.
Also skip backend reprogramming

12a8bd8862 drm/amd/display: Use context parameters to enable FBC
[What]
FBC fails to get enabled when switched between LINEAR(console/VT)
and non-LINEAR(GUI) based rendering due to default value of
tiling info stored in the current_state which is used for deciding
whether or not to turn FBC on or off.

[How]
Use context structure's tiling information which is coherant with
the screen updates.

c69dffab81 drm/amd/display: fix eDP fast bootup for pre-raven asic
[Why]
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.

ceb3dbb469 drm/amd/display: remove sink reference in dc_stream_state
[why]
dc_stream_state containing a pointer to sink is poor design.
Sink describes the display, and the specifications or capabilities
it has.  That information is irrelevant for dc_stream_state, which describes
hardware state, and is generally used for hardware programming.  It
could further be argued that dc_sink itself is just a convenience dc
provides, and DC should be perfectly capable of programming hardware
without any dc_sinks (for example, emulated sinks).

[how]
Phase 1:
Deprecate use of dc_sink pointer in dc_stream.  Most references are trivial
to remove, but some call sites are risky (such as is_timing_changed) with
no obvious logical replacement.  These will be removed in follow up change.

Add dc_link pointer to dc_stream.  This is the typical reason DC really needed
sink pointer, and most call sites are replaced with this.

DMs also need minor updates, as all 3 DMs leverage stream->sink for
some functionality.  this is replaced instead by a pointer to private data
inside dc_stream_state, which is used by DMs as a quality of life improvment
for some key functionality.  it allows DMs to set pointers have to their own objects
which associate OS objects to dc_stream_states (such as DisplayTarget
and amdgpu_dm_connector).  Without the private pointer, DMs would be
forced to perform a lookup for callbacks.

37cd85ce33 drm/amd/display: Remove dc_stream_state->status
[Why]
dc_state has an array of dc_stream_status that contain
pointers to the dc_plane_state and other useful information

Confusingly, dc_stream_state also contains a dc_stream_status
called status.  This struct was partially initialized and
used in a few places

[How]
stream->status.link has been replaced with stream->sink->link.
If a stream does not have a sink, or a sink does not have a link,
something has gone seriously wrong

All other properties of stream->status were zeroed by kzalloc
and never initialized, so they have been replaced by the number 0

This is a refactor: no functional change is intended

599760d6d0 drm/amd/display: Fix Vega10 lightup on S3 resume
[Why]
There have been a few reports of Vega10 display remaining blank
after S3 resume. The regression is caused by workaround for mode
change on Vega10 - skip set_bandwidth if stream count is 0.
As a result we skipped dispclk reset on suspend, thus on resume
we may skip the clock update assuming it hasn't been changed.
On some systems it causes display blank or 'out of range'.

d82f99422b drm/amd/display: move edp fast boot optimization flag to stream
[Why]
During S4/S3 stress test it is possible to resume from S4 without
calling mode set on eDP, meaning high level optimization flag is not
reset. If this is followed by an S3 resume call, driver will see
optimization flag is set and consume it and think backend is powered
on when in fact it is not.

This results in PHY being off in sequence where
S4->Resume->S3->Resume->ApplyOpt->black screen.

[How]
Move optimization flag to stream instead of a DC flag.

c85e6e546e drm/amd/display: Create new i2c resource
[Why]
I2C code did not match dc resource model and was generally
unpleasant

[How]
Move code into new svelte dce_i2c files, replacing various i2c
objects with two structs: dce_i2c_sw and dce_i2c_hw.  Fully split
sw and hw code paths.  Remove all redundant declarations.  Use
address lists to distinguish between versions.  Change dce80 code
to newer register access macros.

5a83c93249 drm/amd/display: Add support for toggling DFS bypass
[Why]

If the hardware supports DFS bypass it will always be enabled after
creation of the DCCG. DFS bypass should only be enabled when
the current stream consists of a single embedded panel and the
minimum display clock is below the DFS bypass threshold.

[How]

Add a function to the DCCG table that updates the DFS bypass state
when setting the bandwidth. If the DFS bypass state is changed, the
clock needs to be reprogrammed to reflect this before the DPREFCLK
is updated for audio endpoints. The existing display clock value
is used as the target display clock value when reprogramming since the
resulting change will be equal or larger to the current value.

These changes only specifically target dce110 but do offer a framework
for support on other applicable targets.

ad8960a6cb drm/amd/display: Check if clock source in use before disabling
[why]
We are disabling clock source while other pipes are still using
it, because we don't verify the number of pipes that share it.

[how]
- Adding a function in resources to return the number of pipes
sharing the clock source.
- Checking that no one is sharing the clock source before disabling

5ae6fe5729 drm/amd/display: Use calculated disp_clk_khz value for dce110
[Why]

The calculated values for actual disp_clk_khz were ignored when
notifying pplib of the new display requirements. In order to honor DFS
bypass clocks from the hardware, the calculated value should be used.

[How]

The return value for set_dispclk is now assigned back into new_clocks
and correctly carried through into dccg->clks.phyclk_khz. When notifying
pplib of new display requirements dccg->clks.phyclk_khz is used
instead of dce.dispclk_khz. The value of dce.dispclk_khz was never
explicitly set to anything before.

A 15% higher display clock value than calculated is no longer requested
for dce110 since it now makes use of the calculated value.

Since dce112 makes use of dce110's set_bandwidth but not its
update_clocks it needs to have the value correctly carried through.
