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.
Rev15:
-Rebase
