If while we are cancelling the breadcrumb signaling, we find that the
request is already completed, move it to the irq signaler and let it be
signaled.
v2: Tweak reference counting so that we only acquire a new reference on
adding to a signal list, as opposed to a hidden i915_request_put of the
caller's reference.

Prevent the ICL HDR plane pipeline from performing YUV color range
correction twice when the input is in limited range. This is done by
removing the limited-range code from icl_program_input_csc().
Before this patch the following could happen: user space gives us a YUV
buffer in limited range; per the pipeline in [1], the plane would first
go through a "YUV Range correct" stage that expands the range; the plane
would then go through the "Input CSC" stage which would also expand the
range because icl_program_input_csc() would use a matrix and an offset
that assume limited-range input; this would ultimately cause dark and
light colors to appear darker and lighter than they should respectively.
This is an issue because if a buffer switches between being scanned out
and being composited with the GPU, the user will see a color difference.
If this switching happens quickly and frequently, the user will perceive
this as a flickering.

In thunderbolt mode the PHY is owned by the thunderbolt controller.
We are not supposed to touch it. So skip the vswing programming
as well (we already skipped the other steps not applicable to TBT).
Touching this stuff could supposedly interfere with the PHY
programming done by the thunderbolt controller.

Currently, the the input to the pp_od_clk_voltage sysfs interface has
two adjacent separator characters, i.e. "\n\0", then we try to parse an
argument out of the empty string, whereas we really should just ignore
this case, and treat any number of adjacent separators as one separator
for arguments.
We do this here by simply skipping the argument parsing for all
empy-string arguments.
An example test case would be `echo 's 1 900' > pp_od_clk_voltage`
(note the two spaces after the 's'.
This also solves the issue where the written string ends with both a
newline, and a nul-terminator, '\n\0', as is the case for `echo 's 1
900' > pp_od_clk_voltage` since the recent rebase.
Got lost during code rebase/merge. No need to port this to other

In function dsi_pll_calc_dec_frac we are calculating the decimal
div start parameter by dividing the decimal multiple by the
fractional multiplier: the remainder of that operation is stored
to then get programmed to the fractional divider registers of
the PLL.
It's useless to call div_u64_rem to get the remainder and *then*
call div_u64 to get the division result, as the first is already
giving that result: let's fix it by just caring about the result
of div_u64_rem.

This is because lockdep thinks all the locks taken in lock_crtcs() are
the same lock, when they actually aren't. That's because we call
mutex_init() in msm_kms_init() and that assigns one static key for every
lock initialized in this loop. Let's allocate a dynamic number of
lock_class_keys and assign them to each lock so that lockdep can figure
out an AA deadlock isn't possible here.

Now that we're not racing with GPU setup, also fix races of timestamps
against other timestamps. In freedreno CI, we were seeing this path trigger
timeouts on setting the GMU bit, producing:
[drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0
and this triggered especially on the first set of tests right after
boot (it's probably easier to lose the race than one might think,
given that we start many tests in parallel, and waiting for NFS to
page in code probably means that lots of tests hit the same point of
screen init at the same time). As of this patch, the message seems to
have completely gone away.

We were using the same force-poweron bit in the two codepaths, so they
could race to have one of them lose GPU power early.
freedreno CI was seeing intermittent errors like:
[drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0
and this issue could have contributed to it.

Before the offending commit in msm_atomic_commit_tail wait_flush was
called once per frame, after the commit was submitted. After it
wait_flush is also called at the beginning to ensure previous
potentially async commits are done.
For cmd panels the source of wait_flush is a ping-pong irq notifying
a completion. The completion needs to be notified with complete_all so
multiple waiting parties (new async committers) can proceed.

The previous registers were *almost* correct, but instead of
PHYs, they were pointing at DSI PLLs, resulting in the PHY id
autodetection failing miserably.

There is HPD unplug interrupts missed at scenario of an irq_hpd
followed by unplug interrupts with around 10 ms in between.
Since both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts,
irq_hpd handler should not issues either aux or sw reset to avoid
following unplug interrupt be cleared accidentally. This patch
also postpone handling of irq_hpd until connected state if it
happened at connection pending state.
Changes in V2:
-- add postpone handling of irq_hpd until connected state
-- check DP_TRAINING_1 instead of DP_TRAINING_NONE

The call to dpu_encoder_phys_cmd_prepare_for_kickoff is useless as
it's unused because the serialize_wait4pp variable is never set to
true by .. anything, literally: remove the call.
While at it, also reduce indentation by inverting the check for
dpu_encoder_phys_cmd_is_master.

When configuring the tearcheck, the parameters for the engine were
being set mostly as they should've been, but then it wasn't getting
configured to get the vsync indication from the TE GPIO input
because it was assumed that autorefresh could be enabled:
since a previous commit makes sure to disable the autorefresh bit
when committing to the cmd engine, it is now safe to just enable
the vsync pin input at tearcheck setup time (instead of erroneously
never enabling it).
Also, set the right sync_cfg_height to enable the DPU auto-generated
TE signal in order to avoid stalls in the event that we miss one
external TE signal: this will still trigger recovery mechanisms in
case the display is really unreachable.

When a command mode display is used, it may be retaining the bootloader
configuration which, in most of the cases, enables the autorefresh
feature in order to keep the splash up.
Since there is no autorefresh management in this driver, wire up the
autorefresh ops in the dpu_hw_pingpong and disable the feature when
preparing for cmd commit: instead of disabling it when initializing
the command mode, this road was chosen as to open future possibility
of enabling and managing the autorefresh feature in the driver.

The DSPP_BLK macro was ad-hoc made for SC7180, but this is wrong
because not all of the DPU DSPP versions can use the same DSPP block
configuration, and not all of them have got the same features.
For this reason, add two more params to the DSPP_BLK macro, so that
it is possible to specify the feature mask and the sblk config for
each DSPP.
