I guess intel_cx0_phy_regs.h since you're adding intel_cx0_phy.c where
this is used.
But I'm confused as the next patch adds that. What's the difference
between the two?! And you're actually adding same stuff to both?

XELPDP has C10 and C20 phys from Synopsys to drive displays. Each phy
has a dedicated PIPE 5.2 Message bus for configuration. This message
bus is used to configure the phy internal registers.
XELPDP has C10 phys to drive output to the EDP and the native output
from the display engine. Add structures, programming hardware state
readout logic. Port clock calculations are similar to DG2. Use the DG2
formulae to calculate the port clock but use the relevant pll signals.
Note: PHY lane 0 is always used for PLL programming.
Add sequences for C10 phy enable/disable phy lane reset,
powerdown change sequence and phy lane programming.

v2: Squash patches related to C10 phy message bus and pll
programming support (Jani)
Move register definitions to a new file i.e. intel_cx0_reg_defs.h (Jani)

From: Radhakrishna Sripada <radhakrishna.sripada@intel.com>
Like DG2, we still don't have a proper algorithm that can be used
for calculating PHY settings, but we do have tables of register
values for a handful of the more common link rates. Some support is
better than none, so let's go ahead and add/use these tables when we
can, and also add some logic to hdmi_port_clock_valid() to filter the
modelist to just the modes we can actually support with these link
rates.
Hopefully we'll have a proper / non-encumbered algorithm to calculate
these registers by the time we upstream and we'll be able to replace
this patch with something more general purpose.

C10 phys uses direct mapping internally for voltage and pre-emphasis levels.
Program the levels directly to the fields in the VDR Registers.

Subject: [PATCH 06/20] drm/i915/mtl: Add vswing programming for C10 phys
From: Radhakrishna Sripada <radhakrishna.sripada@intel.com>
C10 phys uses direct mapping internally for voltage and pre-emphasis levels.
Program the levels directly to the fields in the VDR Registers.

From: Mika Kahola @ 2022-10-14 12:47 UTC (permalink / raw)
To: intel-gfx; +Cc: Lucas De Marchi
Display14 introduces a new way to instruct the PUnit with
power and bandwidth requirements of DE. Add the functionality
to program the registers and handle waits using interrupts.
The current wait time for timeouts is programmed for 10 msecs to
factor in the worst case scenarios. Changes made to use REG_BIT
for a register that we touched(GEN8_DE_MISC_IER _MMIO).

From: Mika Kahola @ 2022-10-14 12:47 UTC (permalink / raw)
To: intel-gfx
Create a table for C20 DP1.4, DP2.0 and HDMI2.1 rates.
The PLL settings are based on table, not for algorithmic alternative.
For DP 1.4 only MPLLB is in use.
Once register settings are done, we read back C20 HW state.
BSpec: 64568

To: intel-gfx
PICA is used for DP alt mode and TBT modes. Hotplug interruption is routed
from PICA chip to south display engine and from there to north display
engine. This patch adds functionality to enable hotplug detection for
all Type-C ports (4 ports available).
Differently from HPD in south display, PICA provides a dedicated HPD
control register for each supported port, so we loop over ports
ourselves instead of using intel_hpd_hotplug_enables() or
intel_get_hpd_pins().

Add register writes to enable powering up Type-C subsystem i.e. TCSS.
For MeteorLake we need to request TCSS to power up and check the TCSS
power state after 500 us.
In addition, for PICA we need to set/clear the Type-C PHY ownnership
bit when Type-C device is connected/disconnected.

Unlike previous platforms that used PORT_TX_DFLEXDPSP
for max_lane calculation, MTL uses only PORT_TX_DFLEXPA1
from which the max_lanes has to be calculated.

The above are flags for the PORT_TX_DFLEXPA1 register, so should be
defined next to it.
TGL handles a few more encodings, not sure if that's correct or the
register description, opened a bspec ticket to clarify that.

The function returns the maximum number of lanes, so should be named
accordingly.

The called function handles all the above, so it can be just:

Yes, I will figure out a different name for that function.
