Fixes for v6.9

Display:
- Fixes for PM refcount leak when DP goes to disconnected state and
  also when link training fails. This is also one of the issues found
  with the pm runtime series

- Change permissions of some dpu debugfs entries which write to const
  data from catalog to read-only to avoid protection faults

  case rather than printing when its known to be NULL.
- Bindings fix to add DP node as child of mdss for mdss node

core:

  imx5+a2xx)

Fixes for v6.6-rc5

- fix to not reset the PHY everytime we start link training but only
  do it if link training fails. Without this, the PLL unlocked
  interrupt fires causing "Unexpected DP AUX IRQ 0x01000000 when
  not busy" spam in the logs since last 2-3 cycles
- correct the highest bank bit to match downstream device tree for
  msm8998
- skip the video mode wait if the timing engine is not enabled. This
  was introduced after pre_enable flag for DSI video mode panels
  where we would end up waiting for the video mode done interrupt
  even before enabling timing engine causing error spam and long
  bootup times.
- check the correct return code of irq_of_parse_and_map() in DSI code
- avoid overflow issues in the dpu bandwidth calculation . This was
  exposed for high resolution displays and a critical fix to avoid
  atomic_check failure
- minor fix to add new lines in DP print messages.
- Fix to fail atomic_check() if the resolution exceeds max mdp clk.
  This leads to underflow otherwise if we try to allow that frame.

  linux-firmware and we see no evidence that it should be different
  from other a660 family (a6xx subgen 4) devices
- Submit overhead opts, 1.6x faster for NO_IMPLICIT_SYNC commits with
  100 BOs to 2.5x faster for 1000 BOs

+ Remove name/revn for a690.. we shouldn't be populating these for
  newer devices, for consistency, but it slipped through review

msm-fixes for v6.4-rc3

Display Fixes:

+ Catalog fixes:
 - fix the programmable fetch lines and qos settings of msm8998
   to match what is present downstream
 - fix the LM pairs for msm8998 to match what is present downstream.
   The current settings are not right as LMs with incompatible
   connected blocks are paired
 - remove unused INTF0 interrupt mask from SM6115/QCM2290 as there
   is no INTF0 present on those chipsets. There is only one DSI on
   index 1
 - remove TE2 block from relevant chipsets because this is mainly
   used for ping-pong split feature which is not supported upstream
   and also for the chipsets where we are removing them in this
   change, that block is not present as the tear check has been moved
   to the intf block
 - relocate non-MDP_TOP INTF_INTR offsets from dpu_hwio.h to
   dpu_hw_interrupts.c to match where they belong
 - fix the indentation for REV_7xxx interrupt masks
 - fix the offset and version for dither blocks of SM8[34]50/SC8280XP
   chipsets as it was incorrect
 - make the ping-pong blk length 0 for appropriate chipsets as those
   chipsets only have a dither ping-pong dither block but no other
   functionality in the base ping-pong
 - remove some duplicate register defines from INTF
+ Fix the log mask for the writeback block so that it can be enabled
  correctly via debugfs
+ unregister the hdmi codec for dp during unbind otherwise it leaks
  audio codec devices
+ Yaml change to fix warnings related to 'qcom,master-dsi' and
  'qcom,sync-dual-dsi'

GPU Fixes:

+ fix submit error path leak
+ arm-smmu-qcom fix for regression that broke per-process page tables
+ fix no-iommu crash

This series adds a deadline hint to fences, so realtime deadlines
such as vblank can be communicated to the fence signaller for power/
frequency management decisions.

This is partially inspired by a trick i915 does, but implemented
via dma-fence for a couple of reasons:

1) To continue to be able to use the atomic helpers
2) To support cases where display and gpu are different drivers

See https://patchwork.freedesktop.org/series/93035/

This does not yet add any UAPI, although this will be needed in
a number of cases:

1) Workloads "ping-ponging" between CPU and GPU, where we don't
   want the GPU freq governor to interpret time stalled waiting
   for GPU as "idle" time
2) Cases where the compositor is waiting for fences to be signaled
   before issuing the atomic ioctl, for example to maintain 60fps
   cursor updates even when the GPU is not able to maintain that
   framerate.

Immutable branch with dma-fence deadline hint support between drm-next and driver -next trees.
