[PARCH v2 0/7] drm/msm/dpu: merge dpu_core_irq into dpu_hw_interrupts

[Dmitry Baryshkov]

This patch series reworks DPU's irq handling code by merging
dpu_core_irq into dpu_hw_intr, reworking/dropping irq-related helpers
and wrappers, etc.

Changes since v1:
 - Rework callbacks registration code to allow just single callback per
   interrupt. This removes need to do any memory allocation in reg/unreg
   code and simplifies handling of interrupts.

The following changes since commit 7e0230fd096c03e9662e66150f951075dd16e496:

  drm/msm/mdp5: provide dynamic bandwidth management (2021-06-17 09:51:44 -0700)
