[PATCH 00/17] Ultrajoiner basic functionality series

[Ankit Nautiyal]

This patch series attempts to implement basic support
for Ultrajoiner functionality.

Rev6:
-Upgrade the debugfs functionality to enable the joining of a
specified number of pipes.
-Modify the display helpers reliant on the pipe joiner mechanism
to use number of pipes joined, instead of joiner flag.
-Checkpatch fixes.

Rev7:
-Use struct intel_display, minor refactoring, and rebase.

Rev8:
-Address comments from Ville.
-Simplified debugfs for forcing joiner, and added option to disable
joiner.
-Modified the ultra/bigjoiner helpers as suggested by Ville. 
-Split few of the bigger patches as suggested.

Rev9:
Rebase

Rev10:
-Rebase
-Fix enable_joined_pipes as suggested by Ville, to avoid propagate
is_ultrajoiner.
-Enhance the mask to iterate over joiner pipes, as suggested by Ville.

Rev11:
-Address review comments from Ville
-Split changes to dsc helpers to separate patches

Rev12:
-Move 'Refactor enable_joiner_pipes' earlier than 'Implement hw state
readout and checks for ultrajoiner'.
-Few improvements as suggested in review comments.
-Use --patience for Patch #8 "drm/i915/display: Refactor
enable_joiner_pipes"

Rev13:
-Refactor get_max_compressed_bpp_with_joiner and split changes into 3
patches.

Rev14:
-Fix issues in patches#11~13 for num_joined_pipes = 1.

Ankit Nautiyal (12):
  drm/i915/display_device: Add Check HAS_DSC for bigjoiner
  drm/i915/display_debugfs: Allow force joiner only if supported
  drm/i915/display: Modify debugfs for joiner to force n pipes
  drm/i915/dp: Add helper to compute num pipes required
  drm/i915: Split current joiner hw state readout
  drm/i915/display: Add macro HAS_ULTRAJOINER()
  drm/i915/display: Refactor enable_joiner_pipes
  drm/i915/dp: Refactor joiner max_bpp calculations into separate
    functions
  drm/i915/dp: Use num_joined_pipes in bigjoiner_bw_max_bpp
  drm/i915/dp: Modify compressed bpp limitations for ultrajoiner
  drm/i915/display: Consider ultrajoiner for computing maxdotclock
  drm/i915/intel_dp: Add support for forcing ultrajoiner

Stanislav Lisovskiy (5):
  drm/i915: Add bigjoiner and uncompressed joiner hw readout sanity
    checks

  drm/i915/display/vdsc: Add ultrajoiner support with DSC
  drm/i915/dp: Simplify helper to get slice count with joiner
  drm/i915: Compute config and mode valid changes for ultrajoiner
