Move all the DPLL params->DPLL frequency conversion functions to
intel_dpll_mgr.c where the corresponding inverse conversions are.
The GEN11+ TBT PLL outputs multiple frequencies and for selecting the
one in use we need to check the DDI CLK mux. As part of the DDI clock
logic this selection is kept in intel_ddi.c.

TGL is suffering of timeouts and fifo underruns when disabling
transcoder in MST mode, this is fixed by set TRANS_DDI_MODE_SELECT to
0(HDMI mode) when clearing DDI select.
Although BSpec disable sequence don't require this step, it is a
harmless change and it is also done by Windows driver.
Anyhow HW team was notified about that but it can take some time to
documentation to be updated.
A case that always lead to those issues is:
- do a modeset enabling pipe A and pipe B in the same MST stream
leaving A as master
- disable pipe A, promote B as master doing a full modeset in A
- enable pipe A, changing the master transcoder back to A(doing a
full modeset in B)
- Pow: underruns and timeouts
The transcoders involved will only work again when complete disabled
and their power wells turned off causing a reset in their registers.
v2: Setting TRANS_DDI_MODE_SELECT to default when clearing DDI select
not anymore when disabling TRANS_DDI, both work but this one looks
more safe. (Ville comment)

A recent change in BSpec allow us to change EXTLINE while transcoder
is enabled so this allow us to change it even when doing the first
fastset after taking over previous hardware state set by BIOS.
BIOS don't enable PSR, so if sink supports PSR it will be enabled on
the first fastset, so moving the EXTLINE compute and set to PSR flows
allow us to simplfy a bunch of code.
This will save a lot of time in all the IGT tests that uses CRC, as
when PSR2 is enabled CRCs are not generated, so we switch to PSR1, so
the previous code would compute dc3co_exitline=0 causing a full
modeset that would shutdown pipe, enable and train link.

When moving the pipe disable & co. function calls from
haswell_crtc_disable() into the encoder .post_disable() hooks I
neglected to account for the MST vs. DDI interactions properly.
This now leads us to call these functions two times for the last
MST stream (once from the MST code and a second time from the DDI
code). The calls from the DDI code should only be done for SST
and not MST. Add the proper check for that.
This results in an MCE on ICL. My vague theory is that we turn off
the transcoder clock from the MST code and then we proceed to touch
something in the DDI code which still depends on that clock causing
the hardware to become upset. Though I can't really explain why
Stan's hack of omitting the pipe disable in the MST code would avoid
the MCE since we should still be turning off the transcoder clock.
But maybe there's something magic in the hw that keeps the clock on
as long as the pipe is on. Or maybe the clock isn't the problem and
we now touch something in the DDI disable code that really does need
the pipe to be still enabled.

On TGL the blending of all the streams have moved from DDI to
transcoder, so now every transcoder working over the same MST port must
send its stream to a master transcoder and master will send to DDI
respecting the time slots.
So here adding all the CRTCs that shares the same MST stream if
needed and computing their state again, it will pick the lowest
pipe/transcoder among the ones in the same stream to be master.
Most of the time skl_commit_modeset_enables() enables pipes in a
crescent order but due DDB overlapping it might not happen, this
scenarios will be handled in the next patch.
v2:
- Using recently added intel_crtc_state_reset() to set
mst_master_transcoder to invalid transcoder for all non gen12 & MST
code paths
- Setting lowest pipe/transcoder as master, previously it was the
first one but setting a predictable one will help in future MST e
port sync integration
- Moving to intel type as much as we can
v3:

- Replaced stdbool.h by linux/types.h
- Skip the connector being checked in

simply code
- Added call drm_atomic_add_affected_planes() in
intel_dp_mst_atomic_master_trans_check() as helper could not do it

Move all of haswell_crtc_disable() into the encoder
.post_disable() hooks. Now we're left with just
calling the .disable() and .post_disable() hooks
back to back.
I chose to move the code into the .post_disable() hook instead
of the .disable() hook as most of the sequence is currently
implemented in the .post_disable() hook.
We should collapse it all down to just one hook and then the
encoders can drive the modeset sequence fully. But that may
need some further refactoring as we currently call the
ddi .post_disable() hook from mst code and we can't just
replace that with a call to the ddi .disable() hook.
Should also follow up with similar treatment for the enable
sequence but let's start here where it's easier.

The MSA MISC computation now depends on the connector state, and
we do it from the DDI .pre_enable() hook. All that is fine for
DP SST but with MST we don't actually pass the connector state
to the dig port's .pre_enable() hook which leads to an oops.
Need to think more how to solve this in a cleaner fashion, but
for now let's just add a NULL check to stop the oopsing.

crtc_state->limited_color_range only applies to RGB output but
we're currently setting it even for YCbCr output. That will
lead to conflicting MSA and PIPECONF settings which can mess
up the image. Let's make sure limited_color_range stays unset
with YCbCr output.
Also WARN if we end up with such a bogus combination when
programming the MSA MISC bits as it's impossible to even
indicate quantization rangle for YCbCr via MSA MISC. YCbCr
output is simply assumed to be limited range always. Note
that VSC SDP does provide a mechanism for full range YCbCr,
so in the future we may want to rethink how we compute/store
this state.

Gen 12 onwards moves the DP_TP_* registers to be transcoder-based rather
than port-based. This adds the new register addresses and changes all
the callers to use the register saved in intel_dp->regs.*. This is
filled out when preparing to enable the port so we take into account if
we should use the transcoder or the port.

To reduce the number of explicit dev_priv->uncore calls in the display
code ahead of the introduction of dev_priv->de_uncore, this patch
introduces a wrapper for one of the main usages of it, the register
waits. When we transition to the new uncore, we can just update the
wrapper to point to the appropriate structure.
Since the vast majority of waits are on a set or clear of a bit or mask,
add set & clear flavours of the wrapper to simplify the code.

When getting the pipes attached to encoder if it is not a eDP encoder
it iterates over all pipes and read a transcoder register.
But it should not read a transcoder register before get its power
domain.
It was not a issue in gens older than 12 because if it only had
port A connected it would be attached to EDP and it would skip all
the transcoders readout, if it had more than one port connected,
pipe B would cause PG3 to be on and it contains all other
transcoders.
But on gen 12 there is no EDP transcoder so it is always iterating
over all pipes and if only one sink is connected, PG3 is kept off
and reading other transcoders registers would cause a
unclaimed read warning.
So here getting the power domain of the transcoder only if it is
enabled, otherwise it is not connected to the DDI.

Right now we are aware of two cases that needs another hotplug retry:
- Unpowered type-c dongles
- HDMI slow unplug
Both have a complete explanation in the code to schedule another run
of the hotplug handler.
It could have more checks to just trigger the retry in those two
specific cases but why would sink signal a long pulse if there is
no change? Also the drawback of running the hotplug handler again
is really low and that could fix another cases that we are not
aware.
Also retrying for old DP ports(non-DDI) to make it consistent and not
cause CI failures if those systems are connected to chamelium boards
that will be used to simulate the issues reported in here.

Convert the code that operates directly on gen11 combo PHY's to use the
new namespace. Combo PHY registers are those named "ICL_PORT_*" plus
ICL_DPHY_CHKN.
Note that a lot of the PHY programming happens in the MIPI DSI code.
For clarity I've added a for_each_dsi_phy() to loop over the phys used
by DSI. Since DSI always uses A & B on gen11, port=phy in all cases so
it doesn't actually matter which form we use in the DSI code. I've used
the phy iterator in code that's explicitly working with the combo PHY,
but left the rest of the DSI code using the port iterator and namespace
to minimize patch deltas. We can switch the rest of the DSI code over
to use phy terminology later if this winds up being too confusing.
v6: Drop an include of drm/i915_drm.h; that was previously included just
for the definition of 'enum port' which this patch removes the need
for. (Jose)

Although the register name implies that it operates on DDI's,
DPCLKA_CFGCR0_ICL actually needs to be programmed according to the PHY
that's in use. I.e., when using EHL's DDI-D on combo PHY A, the bits
described as "port A" in the bspec are what we need to set. The bspec
clarifies:
"[For EHL] DDID clock tied to DDIA clock, so DPCLKA_CFGCR0 DDIA
Clock Select chooses the PLL for both DDIA and DDID and drives
port A in all cases."
Also, since the CNL DPCLKA_CFGCR0 bit defines are still port-based, we
create separate ICL-specific defines that accept the PHY rather than
trying to share the same bit definitions between CNL and ICL.
v5: Make icl_dpclka_cfgcr0_clk_off() take phy rather than port. When
splitting the original patch the hunk to handle this wound up too
late in the series. (Sparse)
v6: Since we're already changing this code,
s/DPCLKA_CFGCR0_ICL/ICL_DPCLKA_CFGCR0/ for consistency. (Jose)

PORT_TX_DFLEXDPMLE1 is a FIA register so move it to intel_tc.c where we
access other FIA registers. In Tiger Lake we have multiple/modular FIAs
so it makes sense to start moving all access to their registers to a
common place.
While at it, make it clear that we will only ever call this function
for ports with TC phy. Previously we were relying on tc_mode being
TC_PORT_TBT_ALT for combo phy ports. However it's confusing since in
this same function we have checks for is_tc_port. Also, if we manage to
make each phy access only their own field, we may in future add them as
a union inside intel_digital_port.
