+ Fix adreno_is_a690() warnings
+ More generic (DRM) and MSM-specific DSC helpers

DP:
+ Removed obsolete USB-PD remains
+ Documented DP compatible string for sm8550 platform

DPU:
+ Enable missing features (DSPP, DSC, split display) on sc8180x,
  sc8280xp, sm8450
+ Enabled writeback on sc7280
+ Implemented tearcheck support to support vsync on SM150 and
  newer platforms
+ Native HDMI output support
+ Dropped unused features: regdma, GC, IGC
+ Fixed the DSC flush operations
+ Simplified QoS handling, removing obsolete and unused features
  and merging SSPP and WB code paths
+ Reworked dpu_encoder initialisation path
+ Enabled DSPP support on sdm845
+ Disabled color-management if DSPP blocks are not available
+ Added support for DSC 1.2 blocks found on sm8350 and later
+ Added .fb_dirty to fix CMD panels

DSI:
+ Drop powerup quirks in favour of using pre_enable_prev_first for
  downstream bridges
+ Fixed 14nm DSI PHY programming
+ Added support for DSI and 28nm DSI PHY on MSM8226 platform
+ Make use of DRM and MSM DSC helpers

MDP5:
+ Added support for display controller on MSM8226 platform

GPU:
+ A690 support
+ Don't set IO_PGTABLE_QUIRK_ARM_OUTER_WBWA on devices with coherent SMMU
  (like A690)
+ Move cmdstream dumping out of fence signaling path
+ Cleanups
