[00/14] Ultrajoiner basic functionality series

Message

Nautiyal, Ankit K Sept. 6, 2024, 12:57 p.m. UTC

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.
