dbc7bb1a93 drm/msm/dpu: filter out too wide modes if no 3dmux is present 
On chipsets such as QCS615, there is no 3dmux present. In such
a case, a layer exceeding the max_mixer_width cannot be split,
hence cannot be supported.

Filter out the modes which exceed the max_mixer_width when there
is no 3dmux present. Also, add a check in the dpu_crtc_atomic_check()
to return failure for such modes.

d9f55e2abf drm/msm/dpu1: don't choke on disabling the writeback connector 
During suspend/resume process all connectors are explicitly disabled and
then reenabled. However resume fails because of the connector_status check:

[dpu error]connector not connected 3
[drm:drm_mode_config_helper_resume [drm_kms_helper]] *ERROR* Failed to resume (-22)

It doesn't make sense to check for the Writeback connected status (and
other drivers don't perform such check), so drop the check.

It wasn't a problem before the commit 71174f362d ("drm/msm/dpu: move
writeback's atomic_check to dpu_writeback.c"), since encoder's
atomic_check() is called under a different conditions that the
connector's atomic_check() (e.g. it is not called if there is no
connected CRTC or if the corresponding connector is not a part of the
new state).

dp_ctrl_off_link() was created to handle a case where we received
a cable connect and then get a cable disconnect without the corresponding
dp_display_enable(). For such cases the pixel clock will be off but the
link clock will still be on. dp_ctrl_off_link() handles this case by
turning off the link clock only.

However, the vote removal to the opp table for this case was missed.

ce55101e6b drm/msm/dpu: fix x1e80100 intf_6 underrun/vsync interrupt 
The IRQ indexes for the intf_6 underrun/vsync interrupts are swapped.
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 16) is the actual underrun interrupt and
DPU_IRQ_IDX(MDP_SSPP_TOP0_INTR, 17) is the vsync interrupt.

This causes timeout errors when using the DP2 controller, e.g.
  [dpu error]enc37 frame done timeout
  *ERROR* irq timeout id=37, intf_mode=INTF_MODE_VIDEO intf=6 wb=-1, pp=2, intr=0
  *ERROR* wait disable failed: id:37 intf:6 ret:-110

dbbf57dfd0 drm/msm/dpu: split dpu_plane_atomic_check() 
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.

8f15005783 drm/msm/dpu: move scaling limitations out of the hw_catalog 
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

20c7b42d9d drm/msm/dpu: cast crtc_clk calculation to u64 in _dpu_core_perf_calc_clk() 
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.

fb7d509b17 drm/msm/dp: prefix all symbols with msm_dp_ 
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.

28edaacb82 drm: zynqmp_dp: Add debugfs interface for compliance testing 
Add a debugfs interface for exercising the various test modes supported
by the DisplayPort controller. This allows performing compliance
testing, or performing signal integrity measurements on a failing link.
At the moment, we do not support sink-driven link quality testing,
although such support would be fairly easy to add.

Additionally, add some debugfs files for ignoring AUX errors and HPD
events, as this can allow testing with equipment that cannot emulate a
DPRX.

a7d5eeaa57 drm: zynqmp_dp: Add locking 
Add some locking to prevent the IRQ/workers/bridge API calls from stepping
on each other's toes. This lock protects:

- Non-atomic registers configuring the link. That is, everything but the
  IRQ registers (since these are accessed in an atomic fashion), and the DP
  AUX registers (since these don't affect the link). We also access AUX
  while holding this lock, so it would be very tricky to support.
- Link configuration. This is effectively everything in zynqmp_dp which
  isn't read-only after probe time. So from next_bridge onward.

This lock is designed to protect configuration changes so we don't have to
do anything tricky. Configuration should never be in the hot path, so I'm
not worried about performance.
