FIA based on pre-assigned offset in GTTMADDR space.
Each Modular FIA instance has its own IOSF Sideband Port ID
and it houses only 2 Type-C Port. In SOC that has more than
two Type-C Ports, there are multiple instances of Modular FIA.
Gunit will need to use different destination ID when it access
different pair of Type-C Port.
The DFLEXDPSP register has Modular FIA bit starting on Tiger Lake. If
Modular FIA is used in the SOC, this register bit exists in all the
instances of Modular FIA. IOM FW is required to program only the MF bit
in first FIA instance that houses the Type-C Port 0 and Port 1, for
Display Driver to read from.
v2 (Lucas):
- Move all accesses to FIA to be contained in intel_tc.c, along with
display_fia that is now called tc_phy_fia
- Save the fia instance number on intel_digital_port, so we don't have

drm/i915/tgl: Add power well support
The patch adds the new power wells introduced by TGL (GEN 12) and
maps these to existing/new power domains. The changes for GEN 12 wrt
to GEN 11 are the following:
- Transcoder#EDP removed from power well#1 (Transcoder#A used in
low-power mode instead)
- Transcoder#A is now backed by power well#1 instead of power well#3
- The DDI#B/C combo PHY ports are now backed by power well#1 instead of
power well#3
- New power well#5 added for pipe#D functionality (TODO)
- 2 additional TC ports (TC#5-6) backed by power well#3, 2 port
specific IO power wells (only for the non-TBT modes) and 4 port
specific AUX power wells (2-2 for TBT vs. non-TBT modes)
- Power well#2 backs now VDSC/joining for pipe#A instead of VDSC for
eDP and MIPI DSI (TODO)
On TGL Port DDI#C changed to be a combo PHY (native DP/HDMI) and
BSpec has renamed ports DDI#D-F to TC#4-6 respectively. Thus on ICL we
have the following naming for ports:
- Combo PHYs (native DP/HDMI):
DDI#A-B
- TBT/non-TBT (TC altmode, native DP/HDMI) PHYs:
DDI#C-F
Starting from GEN 12 we have the following naming for ports:
- Combo PHYs (native DP/HDMI):
DDI#A-C
- TBT/non-TBT (TC altmode, native DP/HDMI) PHYs:
DDI TC#1-6
To save some space in the power domain enum the power domain naming in
the driver reflects the above change, that is power domains TC#1-3 are
added as aliases for DDI#D-F and new power domains are reserved for
TC#4-6.
v2 (Lucas):
- Separate out the bits and definitions for TGL from the ICL ones.
Fix use of TRANSCODER_EDP_VDSC, that is now the correct define since
we don't define TRANSCODER_A_VDSC power domain to spare a one bit in
the bitmask (suggested by Ville)
v3 (Lucas):
- Fix missing squashes on v2
- Rebase on renamed TRANSCODER_EDP_VDSC

drm/i915: Copy name string into ring buffer for intel_update/disable_plane tracepoints
Currently the intel_update_plane and intel_disable_plane tracepoints record
the address of plane->name in the ring buffer, and then when reading the
ring buffer uses %s to get the name. The issue with this, is that those two
events can be minutes, hours or even days apart. It is very dangerous to
dereference a string pointer without knowing if it still exists or not.
The proper way to handle this is to use the __string() macro in the
tracepoint which will save the string into the ring buffer at the time of
recording. Then there's no worries if the original string still exists in
memory when the ring buffer is read.

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.

drm/i915/gen11: Program ICL_DPCLKA_CFGCR0 according to PHY
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

trying to share the same bit definitions between CNL and ICL.

drm/i915/gen11: Start distinguishing 'phy' from 'port'
Our past DDI-based Intel platforms have had a fixed DDI<->PHY mapping.
Because of this, both the bspec documentation and our i915 code has used
the term "port" when talking about either DDI's or PHY's; it was always
easy to tell what terms like "Port A" were referring to from the
context.
Unfortunately this is starting to break down now that EHL allows PHY-A
to be driven by either DDI-A or DDI-D. Is a setup with DDI-D driving
PHY-A considered "Port A" or "Port D?" The answer depends on which
register we're working with, and even the bspec doesn't do a great job
of clarifying this.
Let's try to be more explicit about whether we're talking about the DDI
or the PHY on gen11+ by using 'port' to refer to the DDI and creating a
new 'enum phy' namespace to refer to the PHY in use.
This patch just adds the new PHY namespace, new phy-based versions of
intel_port_is_*(), and a helper to convert a port to a PHY.
Transitioning various areas of the code over to using the PHY namespace
will be done in subsequent patches to make review easier. We'll remove
the intel_port_is_*() functions at the end of the series when we
transition all callers over to using the PHY-based versions.
v2:
- Convert a few more 'port' uses to 'phy.' (Sparse)
v3:
- Switch DDI_CLK_SEL() back to 'port.' (Jose)
- Add a code comment clarifying why DPCLKA_CFGCR0_ICL needs to use PHY
for its bit definitions, even though the register description is
given in terms of DDI.
- To avoid confusion, switch CNL's DPCLKA_CFGCR0 defines back to using
port and create separate ICL+ definitions that work in terms of PHY.
v4:
- Rebase and resolve conflicts with Imre's TC series.
- This patch now just adds the namespace and a few convenience
functions; the important changes are now split out into separate
patches to make review easier.

drm/i915/userptr: Acquire the page lock around set_page_dirty()
set_page_dirty says:
For pages with a mapping this should be done under the page lock
for the benefit of asynchronous memory errors who prefer a
consistent dirty state. This rule can be broken in some special
cases, but should be better not to.
Under those rules, it is only safe for us to use the plain set_page_dirty
calls for shmemfs/anonymous memory. Userptr may be used with real
mappings and so needs to use the locked version (set_page_dirty_lock).
