So far if we had a mismatch between the state asked and what was
programmed in hardware for PSR, this mismatch would go unnoticed.
So here adding the PSR to the hardware configuration readout,
EDP_PSR_CTL and EDP_PSR2_CTL can't be directly read because its state
flips due to other factors like frontbuffer modifications and CRC.

While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:
1) Why is the == comparison special that deserves a separate
macro instead of just getting the version and comparing directly
like is done for >, >=, <=?
2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
brevity. If we remove the current users of IS_DISPLAY_VER(), we
could actually repurpose it for a range check
With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.
So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:

In order to avoid excessive boilerplate I changed the behaviour
such that all platforms now do the readout via
crtc_state->port_dpll[].
ICL+ TC is still a bit special due to TBTPLL not having a functional

move the pipe enable/disable tracepoints to the other side
of the drm_vblank_{on,off}() calls. There shouldn't really be
much happening between these old and new call sites so the
tracepoints should still provide reasonable data.
The alternative would be to give up on having the frame counter

and ICL_DPCLKA_CFGCR0_TC_CLK_OFF part form icl_{map,unmap}_plls_to_ports()
2) ICL/TGL combo DDI + combo PHY
-> just need the stuff from icl_{map,unmap}_plls_to_ports()
3) JSL/EHL TC DDI + combo PHY
-> needs DDI_CLK_SEL==MG part from intel_ddi_clk_{select,disable}() and
the full combo style clock selection from icl_{map,unmap}_plls_to_ports()
4) ADLS/RKL
-> these use both TC and combo DDIs with combo PHYs, however they
always use the full combo style clock selection as per
icl_{map,unmap}_plls_to_ports() and do not use DDI_CLK_SEL at all,

2) icl_ddi_combo_{enable,disable}_clock()

Currently the DPLL .get_freq() uses pll->state.hw_state which
is not the thing we actually read out (except during driver

thing we committed last time around. During state check we
just read the thing into crtc_state->dpll_hw_state, so that
is what we should use for calculating the DPLL output frequency.
I think we used to do this so that the results of the readout
were actually used, but somehow it got changed when the

ICL is a bit special since it already has the two different types
of DDIs (combo or TC) but it still calls them just DDI A-F regarless

Atm, if a full modeset is performed during the initial modeset the link
training will happen with uninitialized max DP rate and lane count. Make
sure the corresponding encoder state is initialized by adding an encoder
hook called during driver init and system resume.
A better alternative would be to store all states in the CRTC state and
make this state available for the link re-training code. Also instead of
the DPCD read in the hook there should be really a proper sink HW
readout in place. Both of these require a bigger rework, so for now opting
for this minimal fix to make at least full initial modesets work.

On HP 800 G4 DM, if HDMI cable isn't plugged before boot, the HDMI port
becomes useless and never responds to cable hotplugging:
[ 3.031904] [drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon
[ 3.031945] [drm:intel_ddi_init [i915]] *ERROR* LSPCON init failed on port D
Seems like the lspcon chip on the system only gets powered after the
cable is plugged.
Consilidate lspcon_init() into lspcon_resume() to dynamically init
lspcon chip, and make HDMI port work.
v6:
- Rebase on latest for-linux-next.
v5:
- Consolidate lspcon_resume() with lspcon_init().
- Move more logic into lspcon code.
v4:
- Trust VBT in intel_infoframe_init().
- Init lspcon in intel_dp_detect().
v3:
- Make sure it's handled under long HPD case.
v2:
- Move lspcon_init() inside of intel_dp_hpd_pulse().

Now that we've plumbed the crtc state all the way down we can
eliminate the DP_TP_{CTL,STATUS} register offsets from intel_dp,
and instead we derive them directly from the crtc state.
And thus we can get rid of the nasty hack in intel_ddi_get_config()
which mutates intel_dp during the readout.

Get rid of mode crtc->config usage, and some ad-hoc intel_dp state
usage by plumbing the crtc state all the way down to the link training

Unfortunately we do have to keep some cached state in intel_dp so

the short hpd handler.

The HDMI vs. not-HDMI check got inverted whem the bogus encoder->type
checks were eliminated. So now we're using 0 as the link rate on DP
and potentially non-zero on HDMI, which is exactly the opposite of
what we want. The original bogus check actually worked more correctly
by accident since if would always evaluate to true. Due to this we
now always use the RBR/HBR1 vswing table and never ever the HBR2+
vswing table. That is probably not a good way to get a high quality
signal at HBR2+ rates. Fix the check so we pick the right table.

the hti_state in dev_priv will remain 0 for platforms it does not
apply to.

Hours Of Battery Life is a new GEN12+ power-saving feature that allows
supported motherboards to use a special voltage swing table for eDP
panels that uses less power.
So here if supported by HW, OEM will set it in VBT and i915 will try
to train link with HOBL vswing table if link training fails it fall
back to the original table.
intel_ddi_dp_preemph_max() was optimized to only check the HOBL flag
instead of do something like is done in intel_ddi_dp_voltage_max()
because it is only called after the first entry of the voltage swing
table was loaded so the HOBL flag is valid at that point.
v3:
- removed a few parameters of icl_ddi_combo_vswing_program() that
can be taken from encoder
v4:

- duplicated the HOBL voltage swing entry to match DP spec requirement

- changed from u8:1 to bool to store hobl_failed/active

One example where the above overwite happens is the encoder HW state

Let's get rid of the platform if ladders in
intel_digital_port_connected() and make it a vfunc. Now the if
ladders are at the encoder initialization which makes them a bit
less convoluted.
v2: Add forward decl for intel_encoder in intel_tc.h
v3: Duplicate stuff to avoid exposing platform specific
functions across files (Jani)

Remove a number of inlines from .c files, and let the compiler decide
what's best. There's more to do, but need to start somewhere, and need
to start setting the example.

Pass the encoder all the way down to
intel_ddi_transcoder_func_reg_val_get(). Allows us eliminate the
intel_ddi_get_crtc_encoder() eyesore.

Push the TRANS_DDI_FUNC_CTL into the encoder enable hook. The disable
is already there, and as a followup will enable us to pass the encoder
all the way down.
