Joiners have specific enabling and disabling order dependent on primary and secondary pipes. This becomes more complex with ultrajoiner where we have ultrajoiner primary/secondary pipes in addition to bigjoiner primary/secondary pipes. To unify the approach that works for present and future joiner cases, use primary and secondary pipe masks to iterate over pipes. If joiner is used, derive bigoiner primary and secondary pipe masks and use following sequences: Disabling : disable primary pipes followed by secondary pipes, Enabling: enable secondary pipes followed by primary pipes. This works well with ultrajoiner too, as ultrajoiner has 2 bigjoiner primary/secondary pairs (AC, BD). For non joiner case, enable/disable based on usual pipe order A-D, D-A respectively. v2: -Simplify the iterator macro. (Ville) -Use struct intel_display. (Ville) -Add prefix _intel to the helper name.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
