This patch series attempts to implement basic support for Ultrajoiner functionality. Patches 1-2 are re-posts from https://patchwork.freedesktop.org/series/138751/ 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.
