Move existing register definitions to mdss.xml and use generated defines
for registers access instead of hand-coding everything in the source
file.

Move a call to dpu_plane_check_inline_rotation() to the
dpu_plane_atomic_check_sspp() function, so that the rot90 constraints
are checked for both SSPP blocks. Also move rotation field from struct
dpu_plane_state to struct dpu_sw_pipe_cfg.

Split dpu_plane_atomic_check() function into two pieces:
dpu_plane_atomic_check_nosspp() performing generic checks on the pstate,
without touching the associated SSPP blocks,
and
dpu_plane_atomic_check_sspp(), which takes into account used SSPPs.

Max upscale / downscale factors are constant between platforms. In
preparation to adding support for virtual planes and allocating SSPP
blocks on demand move max scaling factors out of the HW catalog and
handle them in the dpu_plane directly. If any of the scaling blocks gets
different limitations, this will have to be handled separately, after
the plane refactoring.

The virt_formats / virt_num_formats are not used by the current driver
and are not going to be used in future since formats for virtual planes
are handled in a different way, by forbidding unsupported combinations
during atomic_check. Drop those fields now.

Since commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") a mmap() of anonymous memory without a specific address hint
and of at least PMD_SIZE will be aligned to PMD so that it can benefit
from a THP backing page.
However this change has been shown to regress some workloads
significantly. [1] reports regressions in various spec benchmarks, with
up to 600% slowdown of the cactusBSSN benchmark on some platforms. The
benchmark seems to create many mappings of 4632kB, which would have merged
to a large THP-backed area before commit efa7df3e3bb5 and now they are
fragmented to multiple areas each aligned to PMD boundary with gaps
between. The regression then seems to be caused mainly due to the
benchmark's memory access pattern suffering from TLB or cache aliasing due
to the aligned boundaries of the individual areas.
Another known regression bisected to commit efa7df3e3bb5 is darktable [2]
[3] and early testing suggests this patch fixes the regression there as
well.
To fix the regression but still try to benefit from THP-friendly anonymous
mapping alignment, add a condition that the size of the mapping must be a
multiple of PMD size instead of at least PMD size. In case of many
odd-sized mapping like the cactusBSSN creates, those will stop being
aligned and with gaps between, and instead naturally merge again.

When numa balancing is enabled with demotion, vmscan will call
migrate_pages when shrinking LRUs. migrate_pages will decrement the
the node's isolated page count, leading to an imbalanced count when
invoked from (MG)LRU code.
The result is dmesg output like such:
$ cat /proc/sys/vm/stat_refresh
[77383.088417] vmstat_refresh: nr_isolated_anon -103212
[77383.088417] vmstat_refresh: nr_isolated_file -899642
This negative value may impact compaction and reclaim throttling.
The following path produces the decrement:
shrink_folio_list
demote_folio_list
migrate_pages
migrate_pages_batch
migrate_folio_move
migrate_folio_done
mod_node_page_state(-ve) <- decrement
This path happens for SUCCESSFUL migrations, not failures. Typically
callers to migrate_pages are required to handle putback/accounting for
failures, but this is already handled in the shrink code.
When accounting for migrations, instead do not decrement the count when
the migration reason is MR_DEMOTION. As of v6.11, this demotion logic
is the only source of MR_DEMOTION.

There may be a potential integer overflow issue in
_dpu_core_perf_calc_clk(). crtc_clk is defined as u64, while
mode->vtotal, mode->hdisplay, and drm_mode_vrefresh(mode) are defined as
a smaller data type. The result of the calculation will be limited to
"int" in this case without correct casting. In screen with high
resolution and high refresh rate, integer overflow may happen.
So, we recommend adding an extra cast to prevent potential
integer overflow.

For historical reasons a lot of symbols in the MSM DisplayPort driver
used the generic dp_ prefix. Perform a mass-rename of those symbols to
use msm_dp prefix.
Basically this is a result of the following script:
sed drivers/gpu/drm/msm/dp/* -i -e 's/\<dp_/msm_dp_/g'
sed drivers/gpu/drm/msm/dp/* -i -e 's/"msm_dp_/"dp_/g'
sed drivers/gpu/drm/msm/dp/* -i -e 's/msm_\(dp_sdp_header\|dp_sdp\)\>/\1/g'
Yes, this also results in renaming of several struct fields in addition
to renaming the structs and functions, but I think the simple solution
is better than the more complex one.

error message to kernel log.

The gpiolib debugfs interface exports a list of all gpio chips in a
system and the state of their pins.
The gpio chip sections are supposed to be separated by a newline
character, but a long-standing bug prevents the separator from
being included when output is generated in multiple sessions, making the
output inconsistent and hard to read.
Make sure to only suppress the newline separator at the beginning of the
file as intended.

At least the i-tec USB-C Nano 2x Display Docking Station (containing a
Synaptics MST branch device) requires the driver to update the source
OUI DPCD registers to expose its DSC capability. Accordingly update the
OUI for all sink types (besides eDP where this has been done already).

The DP sink's capabilities, like DSC, may depend on the source OUI
written to the sink. On eDP this OUI value could have been reset before
the detection started if the panel power on it got disabled. Make sure
the OUI is re-written at the beginning of detection in this case, before
the sink capabilities are read out.

While updating the source OUI on the sink the driver should avoid
writing the OUI if it's already up-to-date to prevent the sink from
resetting itself in response to the update. On eDP - the only output
type where the OUI was updated so far - the driver ensured this by
comparing the current source OUI DPCD register values with the expected
Intel OUI value, skipping the update in case of a match. On some non-eDP
sinks - at least on Synaptics branch devices - this method doesn't work,
since the source OUI DPCD registers read back as all 0, even after
updating the registers.
Handle the above kind of sinks by tracking when the OUI was updated and
so should be valid, regardless of what the DPCD registers contain.
eDP sinks reset the written source OUI value when the panel power is
disabled, invalidate the OUI state accordingly.
This is required by a follow-up patch updating the source OUI for
non-eDP sink types as well.
v2: Fix setting intel_dp::oui_valid=true, if the DPCD register contains
already the expected value.

If the source OUI DPCD register value matches the expected Intel OUI
value, the write timestamp doesn't get updated leaving it at the 0
initial value if the OUI wasn't written before. This can lead to an
incorrect wait duration in intel_dp_wait_source_oui(), since jiffies is
not inited to 0 in general (on a 32 bit system INITIAL_JIFFIES is set to
5 minutes ahead of wrap-around). Fix this by intializing the write
timestamp in the above case as well.
