[Intel-gfx] [PATCH 1/3] drm/i915/dg2: Enable 5th display

[Ramalingam C]

From: Matt Roper <matthew.d.roper@intel.com>

DG2 supports a 5th display output which the hardware refers to as "TC1,"
even though it isn't a Type-C output.  This behaves similarly to the TC1
on past platforms with just a couple minor differences:

 * DG2's TC1 bit in SDEISR is at bit 25 rather than 24 as it is on
   ICP/TGP/ADP.
 * DG2 doesn't need the hpd inversion setting that we had to use on DG1

Not sure if this applies to DG1, the 5th TC1 port is only for DG2.  Should we not have a separate
DG2 struct. Can you please clarify to help understand.

It's fine to add this to the DG1 structure since it's just a mapping
table.  DG1 will never use TC1 as an input into the table, but there
aren't any conflicting mappings between DG1/DG2 so we can use the same
table for both.

Re: [Intel-gfx] [PATCH 1/3] drm/i915/dg2: Enable 5th display

[Matt Roper]

Since it apparently caused some confusion on various websites, maybe we
should change the title of the patch to "Enable 5th port" to make it
more clear that this is only a port, not a pipe.

Also, I believe one last line that we need to add to this patch is an
intel_ddi_init() call for TC1 in the intel_setup_outputs() function.  I
think I previously had that in a separate patch, but it went missing
when we reorganized and refactored some of these patches

[Intel-gfx] [PATCH v2 1/3] drm/i915/dg2: Enable 5th port

[Ramalingam C]

From: Matt Roper <matthew.d.roper@intel.com>

DG2 supports a 5th display output which the hardware refers to as "TC1,"
even though it isn't a Type-C output.  This behaves similarly to the TC1
on past platforms with just a couple minor differences:

 * DG2's TC1 bit in SDEISR is at bit 25 rather than 24 as it is on
   ICP/TGP/ADP.
 * DG2 doesn't need the hpd inversion setting that we had to use on DG1

v2:
  intel_ddi_init(dev_priv, PORT_TC1); [Matt]

[Intel-gfx] [PATCH 2/3] drm/i915/dg2: Drop 38.4 MHz MPLLB tables

[Ramalingam C]

From: Matt Roper <matthew.d.roper@intel.com>

Our early understanding of DG2 was incorrect; since the 5th display
isn't actually a Type-C output, 38.4 MHz input clocks are never used on
this platform and we can drop the corresponding MPLLB tables.

[Intel-gfx] [PATCH 3/3] drm/i915: Fix for PHY_MISC_TC1 offset

[Ramalingam C]

From: Jouni Högander <jouni.hogander@intel.com>

Currently ICL_PHY_MISC macro is returning offset 0x64C10 for PHY_E
port. Correct offset is 0x64C14.

Fix this by handling PHY_E port seprately.

Nit: Align it as was defined earlier to honor line limit.

Looks Good to me.

Why is it PHY_E and not PHY_F?

This is a valid question. It seems we have followed intel_phy_is_snps()
here:

// snip
else if (IS_DG2(dev_priv))
		/*
		 * All four "combo" ports and the TC1 port (PHY E) use
		 * Synopsis PHYs.
		 */
		return phy <= PHY_E;
// snip

According to spec port E is "No connection". Better place to fix this
could be intel_phy_is_snps() itself?

I think the crucial question is where are all the places that
the results of intel_port_to_phy() get used.

I do see that for all the actual snps phy registers we
do want PHY_E, but maybe it would be better to have a local
SNPS_PHY enum just for intel_snps_phy.c, and leave the other
phy thing for everything else?

Not sure if there is some other register we index with the
phy that specifically wants PHY_E?

Also it kinda looks to me like for VBT port mapping we also
want PHY_F essentially since the modern platforms make the
VBT port mapping PHY based and xelpd_port_mapping() uses
PORT_TC1<->DVO_PORT_*F. Not that we actually use enum phy
in the VBT code atm, but I'm thinking we probably should
since it might allow us to get rid of all those different
mapping tables. Though the whole intel_port_to_phy()
disaster needs to get cleaned up first IMO.

I went through registers accesses in intel_snps_phy.c. It is actually
only this one register which offset is wrong with PHY_E. Everything
else seems to be assuming PHY_E including those SNPS_* registers (as
you mentioned). I'm starting to think it would be overkill to open up
this phy enum for this purpose. I would propose to stick with current
patch. Maybe just update commit message. What do you think?

I would put it the other way. It is *only* the SNPS PHY IP registers
that use the wonky offsets (unless you found some others?). Everythting
on the Intel IP side wants it to be PHY_F.

So still would make more sense to me to add a new enum for the
SNPS PHY instance and remap across the boundary. Otherwise we're
just propagating this madness everwhere rather than containing in
the SNPS PHY implementation.

Seems people want this is asap. I suppose it'll do as a temporary
measure given the phy stuff is already such mess.
Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com>

As for the proper way to do stuff, I'm thinking roughly:
enum intel_spns_phy {
	SNPS_PHY_A,
	...
	SNPS_PHY_TC1, // == current PHY_E in value
};
and I think that can stay entirely inside intel_snps_phy.c.

As for our currnet enum phy I think we could start with something like
this:
enum phy {
	PHY_A,
	...
	PHY_F,

	PHY_TC1 = PHY_F,
	...
};

I think that should make it line up with PHY_MISC stuff and the 
VBT as well. So in the VBT code we could nuke all those crazy mapping
tables and just do:
 old platform: port -> VBT port
 new platform: phy -> VBT port

And we could probably have encoder->phy which gets populated
in the encoder init per-platform, similar to hpd_pin. That
would get rid of the intel_port_to_phy() disaster.

And this is actually the bug that we had. We wouldn't need to bring the
incomplete support for the 5th port if this single had changed:  it's
often preferred to prepare the driver first and enable the port/phy as
the last step:

-		return phy <= PHY_E;
+		return phy <= PHY_D;

With possibly a change in the commit above. Because in
drivers/gpu/drm/i915/display/intel_snps_phy.c we do:

intel_snps_phy_wait_for_calibration()
{
...
         for_each_phy_masked(phy, ~0) {
                 if (!intel_phy_is_snps(i915, phy))
                         continue;
...
}

Relying on intel_phy_is_snps() to mask out the unavailable phys.

However, since now we almost have the extra port wired up, I'm not going
to push back on it. Let's just add a comment on the commit message.
And since going with this approach is also acked by Ville who preferred
to contain the additional mapping inside intel_phy_snps.c:

order of the patch here is wrong. This patch should come before
the patch initializing the 5th port. Then the commit message is not
a fix.

This can be done while applying since it's more an order to avoid
breaking the tree.
