  drm/msm/dpu: fail dpu_plane_atomic_check() based on mdp clk limits
(2023-10-05 10:18:10 -0700)

----------------------------------------------------------------
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.
