Browse Source 
- Fourcc modifier for tiled but not compressed layouts
- Support for userspace allocated IOVA (GPU virtual address)
- Devfreq clamp_to_idle fix
- DPU: DSC (Display Stream Compression) support
- DPU: inline rotation support on SC7280
- DPU: update DP timings to follow vendor recommendations
- DP, DPU: add support for wide bus (on newer chipsets)
- DP: eDP support
- Merge DPU1 and MDP5 MDSS driver, make dpu/mdp device the master
  component
- MDSS: optionally reset the IP block at the bootup to drop
  bootloader state
- Properly register and unregister internal bridges in the DRM framework
- Complete DPU IRQ cleanup
- DP: conversion to use drm_bridge and drm_bridge_connector
- eDP: drop old eDP parts again
- DPU: writeback support
- Misc small fixes
