drm/i915: Populate encoder->devdata for DSI on icl+
We now have some eDP+DSI dual panel systems floating around
where the DSI panel is the secondary LFP and thus needs to
consult "panel type 2" in VBT in order to locate all the
other panel type dependant stuff correctly.
To that end we need to pass in the devdata to
intel_bios_init_panel_late(), otherwise it'll just assume
we want the primary panel type. So let's try to just populate
the vbt.ports[] stuff and encoder->devdata for icl+ DSI
panels as well.
We can't do this on older platforms as there we risk a DSI
port aliasing with a HDMI/DP port, which is a totally legal

However since we now keep each wm level enabled on a per-plane basis

where another plane can only do WM0 (and thus needs the copy) but

drm/i915/psr: Split sel fetch plane configuration into arm and noarm
SEL_FETCH_CTL registers are armed immediately when plane is disabled.
SEL_FETCH_* instances of plane configuration are used when doing
selective update and normal plane register instances for full updates.
Currently all SEL_FETCH_* registers are written as a part of noarm
plane configuration. If noarm and arm plane configuration are not
happening within same vblank we may end up having plane as a part of
selective update before it's PLANE_SURF register is written.
Fix this by splitting plane selective fetch configuration into arm and
noarm versions and call them accordingly. Write SEL_FETCH_CTL in arm
version.
v3:
- add arm suffix into intel_psr2_disable_plane_sel_fetch
v2:
- drop color_plane parameter from arm part
- dev_priv -> i915 in arm part

drm/i915/pxp: Pxp hw init should be in resume_complete
During suspend flow, i915 currently achors' on the pm_suspend_prepare
callback as the location where we quiesce the entire GPU and perform
all necessary cleanup in order to go into suspend. PXP is also called
during this time to perform the arbitration session teardown (with
the assurance no additional GEM IOCTLs will come after that could
restart the session).
However, if other devices or drivers fail their suspend_prepare, the
system will not go into suspend and i915 will be expected to resume
operation. In this case, we need to re-initialize the PXP hardware
and this really should be done within the pm_resume_complete callback
which is the correct opposing function in the resume sequence to
match pm_suspend_prepare of the suspend sequence.
Because this callback is the last thing at the end of resuming
we expect little to no impact to the rest of the i915 resume sequence
with this change.

However the OS was in a suspended state and GuC had been reset.
Internal specifications actually required the driver to ensure

drm/i915/pxp: Invalidate all PXP fw sessions during teardown
A gap was recently discovered where if an application did not
invalidate all of the stream keys (intentionally or not), and the
driver did a full PXP global teardown on the GT subsystem, we
find that future session creation would fail on the security
firmware's side of the equation. i915 is the entity that needs
ensure the sessions' state across both iGT and security firmware
are at a known clean point when performing a full global teardown.
Architecturally speaking, i915 should inspect all active sessions
and submit the invalidate-stream-key PXP command to the security
firmware for each of them. However, for the upstream i915 driver
we only support the arbitration session that can be created
so that will be the only session we will cleanup.

1) It increases the code size since the array is declared
in each call site
2) Developers need to be careful not to incur an
out-of-bounds array access
3) Developers need to be careful that the indexes match the
table. For that it may be that the table needs to contain
holes, making (1) even worse.

one to use depending on the index value.

drm/i915/display: add intel_display_limits.h for key enums
Move a handful of key enums to a new file intel_display_limits.h. These
are the enum types, and the MAX/NUM enumerations within them, that are
used in other headers. Otherwise, there's no common theme between them.
Replace intel_display.h include with intel_display_limit.h where
relevant, and add the intel_display.h include directly in the .c files
where needed.
Since intel_display.h is used almost everywhere in display/, include it
from intel_display_types.h to avoid massive changes across the
board. There are very few files that would need intel_display_types.h
but not intel_display.h so this is neglible, and further cleanup between
these headers can be left for the future.
Overall this change drops the direct and indirect dependencies on
intel_display.h from about 300 to about 100 compilation units, because
we can drop the include from i915_drv.h.

drm/i915/audio: Don't program the hardware ELD buffer on hsw+
Since we use the audio component to transfer the ELD to the audio
driver on hsw+ platforms there is no point in even programming
the hardware ELD buffer. Stop doing so.
The one slight caveat here is that this is not strictly legal
according to the HDA spec. PD=1;ELD=0 is only documented as
an intermediate state during modeset. But if there is no hardware
that depends on that then I guess we're fine. Or we could
perhaps set ELD=1 without actually programming the buffer?
Note that the bspec sequence of PD=0;ELD=0 -> PD=1;ELD=0 ->
PD=1;ELD=1 is also not strictly correct according to the HDA
spec, as the only documented transition from PD=0;ELD=0 is
straight to PD=1;ELD=1.
Additionally on hsw/bdw the hardware buffer is tied in with the
dedicated display HDA controller's power state, so currently
we mostly fail at proramming the buffer anyway. When the HDA
side is not sufficiently powered up the ELD address bits get
stuck and the ELD data register accesses go nowhere.

New DMC releases in linux-firmware will stop using version number in
blob filenames. This new convention provides the following benefits:
1. It simplifies code maintenance, as new DMC releases for a platform
using the new convention will always use the same filename for the
blob.
2. It allows DMC to be loaded even if the target system does not have
the most recent firmware installed.
Prepare the driver by:
- Using the new convention for DMC_PATH() and renaming the currently
used one to make it clear it is for the legacy scheme.
- Implementing a fallback mechanism for future transitions from
versioned to unversioned paths so that we do not cause a regression
for systems not having the most up-to-date linux-firmware files.
v2:
- Keep using request_firmware() instead of firmware_request_nowarn().

v3:

drm/ssd130x: Silence a `dubious: x & !y` warning
The sparse tool complains with the following warning:
$ make M=drivers/gpu/drm/solomon/ C=2
CC [M] drivers/gpu/drm/solomon/ssd130x.o
CHECK drivers/gpu/drm/solomon/ssd130x.c
drivers/gpu/drm/solomon/ssd130x.c:363:21: warning: dubious: x & !y
This seems to be a false positive in my opinion but still we can silence
the tool while making the code easier to read. Let's also add a comment,
to explain why the "com_seq" logical not is used rather than its value.

fbdev: Remove unused struct fb_deferred_io .first_io field
This optional callback was added in the commit
1f45f9dbb392 ("fb_defio:
add first_io callback") but it was never used by a driver. Let's remove
it since it's unlikely that will be used after a decade that was added.

Simple framebuffers can be set up in system memory, which cannot be
requested and/or I/O remapped using the I/O resource helpers. Add a

drm/simpledrm: Use struct iosys_map consistently
The majority of the driver already uses struct iosys_map to encapsulate
accesses to I/O remapped vs. system memory. Accesses via the screen base
pointer still use __iomem annotations, which can lead to inconsistencies
and conflicts with subsequent patches.
Convert the screen base to a struct iosys_map as well for consistency
and to avoid these issues.
