This patch uses GFFID switch command to scan whether remote device is
Target or Initiator mode. Based on that info, driver will not pass up
Initiator info to authentication application. This helps reduce unnecessary
stress for authentication application to deal with unused connections.

After issuing a LIP, a specific target vendor does not ACC the FLOGI that
lpfc sends. However, it does send its own FLOGI that lpfc ACCs. The
target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs
and starts the RPI registration for DID 0x000001. The target then sends a
LOGO to the fabric DID. lpfc is currently treating the LOGO from the
fabric DID as a link down and cleans up all the ndlps. The ndlp for DID
0x000001 is put back into NPR and discovery stops, leaving the port in
stuck in bypassed mode.
Change lpfc behavior such that if a LOGO is received for the fabric DID in
PT2PT topology skip the lpfc_linkdown_port() routine and just move the
fabric DID back to NPR.

A use-after-free crash can occur after an ELS LOGO is aborted.
Specifically, a nodelist structure is freed and then
ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the
discovery state machine is mistakenly called a second time with
NLP_EVT_DEVICE_RM argument.
Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a
nodelist structure.

Refactoring and consolidation of abort paths:
- lpfc_sli4_abort_fcp_cmpl() and lpfc_sli_abort_fcp_cmpl() are combined
into a single generic lpfc_sli_abort_fcp_cmpl() routine. Thus, remove
extraneous lpfc_sli4_abort_fcp_cmpl() prototype declaration.
- lpfc_nvme_abort_fcreq_cmpl() abort completion routine is called with a
mismatched argument type. This may result in misleading log message
content. Update to the correct argument type of lpfc_iocbq instead of
lpfc_wcqe_complete. The lpfc_wcqe_complete should be derived from the
lpfc_iocbq structure.

Fixing the interpretation of the length of the B9h VPD page (Concurrent
Positioning Ranges). Adding 4 is necessary as the first 4 bytes of the page
is the header with page number and length information. Adding 3 was likely
a misinterpretation of the SBC-5 specification which sets all offsets
starting at zero.

Presently ima_get_kexec_buffer() doesn't check if the previous kernel's
ima-kexec-buffer lies outside the addressable memory range. This can result
in a kernel panic if the new kernel is booted with 'mem=X' arg and the
ima-kexec-buffer was allocated beyond that range by the previous kernel.
The panic is usually of the form below:

The bcm5974 driver does the allocation and dma mapping of the usb urb

Following commit 17e822f7591f ("drm/msm: fix unbalanced
pm_runtime_enable in adreno_gpu_{init, cleanup}"), any call to
adreno_unbind() will disable runtime PM twice, as indicated by the call
trees below:
adreno_unbind()
-> pm_runtime_force_suspend()
-> pm_runtime_disable()
adreno_unbind()
-> gpu->funcs->destroy() [= aNxx_destroy()]
-> adreno_gpu_cleanup()
-> pm_runtime_disable()
Note that pm_runtime_force_suspend() is called right before
gpu->funcs->destroy() and both functions are called unconditionally.
With recent addition of the eDP AUX bus code, this problem manifests
itself when the eDP panel cannot be found yet and probing is deferred.
On the first probe attempt, we disable runtime PM twice as described
above. This then causes any later probe attempt to fail with
[drm:adreno_load_gpu [msm]] *ERROR* Couldn't power up the GPU: -13
preventing the driver from loading.
As there seem to be scenarios where the aNxx_destroy() functions are not
called from adreno_unbind(), simply removing pm_runtime_disable() from
inside adreno_unbind() does not seem to be the proper fix. This is what
commit 17e822f7591f ("drm/msm: fix unbalanced pm_runtime_enable in
adreno_gpu_{init, cleanup}") intended to fix. Therefore, instead check
whether runtime PM is still enabled, and only disable it in that case.

[Why]
In cases where there are multiple eDP instances, DMUB needs to know
which instance the command is for. Today, the field for specifying the
panel_inst exists in both dmub_cmd_update_dirty_rect_data and
dmub_cmd_update_cursor_info_data.
For cursor updates, we already specify the panel_inst, but that's not
the case for dirty_rect updates. Today, a value of '0' is used (due
to initial memsetting of the cmd struct to 0)
[how]
In dc_dmub_update_dirty_rect(), Call dc_get_edp_link_panel_inst() to get
the panel_inst, and fill it in the DMUB cmd struct.

[Why]
PSR-SU Rate Control - or PSR-SU-RC - enables PSR-SU panels to work with
variable refresh rate to allow for more power savings. Lowering the
refresh rate can increase PSR residency by expanding the eDP main link
shut down duration. It can also lower panel power consumption.
There is a complication with PSR, since the eDP main link can be shut
down. Therefore, the timing controller (TCON) on the eDP sink nees to be
able to scan out its remote buffer independent of the main link. To
allow the eDP source to specify the sink's refresh rate while the link
is off, vendor-specific DPCD registers are used. This allows the eDP
source to then "Rate Control" the panel during PSR active.
[How]
Add DC support to communicate with PSR-SU-RC supported eDP sinks. The
sink will need to know the desired VTotal during PSR active.
This change only adds support to DC, support in amdgpu_dm is still
pending to enable this fully.

[Why]
When switching from 1 pipe to 4to1 mpc combine,
DppDtoClk aren't enabled for the disabled pipes
pior to programming the pipes. Upon optimizing
bandwidth, DppDto are enabled causing intermittent
underflow.
[How]
Update dppclk dto whenever pipe are flagged to
enable.

[Why]
For OLED eDP the Display Manager uses max_cll value as a limit
for brightness control.
max_cll defines the content light luminance for individual pixel.
Whereas max_fall defines frame-average level luminance.
The user may not observe the difference in brightness in between
max_fall and max_cll.
That negatively impacts the user experience.
[How]
Use max_fall value instead of max_cll as a limit for brightness control.

[why]
1. When HPD deassertion is pulled in the middle of
enabe stream link training, we will abort current training
and turn off PHY. This causes current link settings
to be zeroed this causes later stream enablement
sequence to fail as we prefer to carry on enablement
process despite of link training failure for SST.
2. When HPD is toggled after detection before before
the enable stream sequence as a result. There could be
a race condition where we could end up enable stream based
on the previous link even though the link is updated
after the HPD toggle. This causes an issue where our link
bandwidth is no longer enough to accommodate the timing
therefore causes us to oversubscribe MST payload time
slots. As discussed we decided to add basic sanity check
to make sure that our code can handle the oversubscription
failure silently without system hang.
[how]
1. Keep PHY powered on when HPD is deasserted during
enable stream and wait for the detection sequence to power
it off later.
2. Do not allocate payload if the required timeslot for
current timing is greater than 64 timeslots.

[Why]
In 3-way mpo pipes, there is a case that we
overbook the CRB buffer size. At rare instances,
overbooking the crb will cause underflow. This only
happens when det_size changes dynamically
based on pipe_cnt.
[How]
Set min compbuff size to 1 segment when preparing BW.

[Why]
For panels with pixel clock > 1200MHz that require ODM
in pre-OS, when driver is disabled in OS, odm is enabled.
Upon driver enablement, corruption is seen if
odm was originally enabled. DP_PIXEL_COMBINE and
pixelclk must be programmed prior to programming the
optc-odm registers. However, eDP displays aren't blanked
prior to initializing odm in this case.
[How]
Upon driver enablement, check whether odm is enabled,
if so, blank eDP prior to programming optc-odm
registers.

[Why]
LTTPR capable devices on the DisplayPort path may assume that
extended LTTPR AUX timeouts will be used after LTTPR capabilities
are read.
When DPTX operates in non-LTTPR mode, AUX timeouts are not
extended and this can result in AUX transactions timing out.
[How]
Use shared helper function to determine LTTPR mode and do not
read LTTPR capabilities in non-LTTPR mode.

Currently set MP5496 Buck and LDO ranges dont match its datasheet[1].
According to the datasheet:
Buck range is 0.6-2.1875V with a 12.5mV step
LDO range is 0.8-3.975V with a 25mV step.
So, correct the ranges according to the datasheet[1].

The intel_dp_dsc_get_output_bpp() function outputs two lines of
unconditional logs, which was okay when it was called only once. But
now, we also call this function from intel_dp_mode_valid(), which is
in turn called for every mode we need to validate. This causes a lot
of useless noise.
Remove the unconditional prints to avoid spamming the logs. Also
remove one more print that is not unconditional, but is related.
