Ville Syrjälä 4c0eb35fc1 drm/i915: Improve PPS debugs
Always include both the encoder and PPS instance information
in the debug prints so that we know what piece of hardware
we're actually dealing with.

v2: Make sure pps is selected before debug prints/etc. in
    intel_pps_vdd_on_unlocked() on vlv/chv
    There is no pps on pipe C on chv
v3: Allow PPS=INVALID_PIPE for vlv/chv

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 Restructured Text 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.
