Ville Syrjälä edba48fdfc drm/i915: Centralize the SKL DDI A/E vs. B/C/D buf trans handling
SKL DDI B/C/D only have 9 usable buf trans registers for DP/eDP. That
matches the normal DP buf trans tables, but the low vswing eDP tables
have 10 entries. Thus the eDP tables can only be used safely with DDI A
and E.

We try to catch cases where DDI B/C/D gets used with the wrong number of
entires in some parts of the code, but not everywhere. Let's move the
code to deal with that deeper into intel_ddi_get_buf_trans_edp(). And
for sake of symmetry do the same in intel_ddi_get_buf_trans_dp(). That
would also avoid explosions in the rather unlikely case that the DP
tables would get revised to 10 entries as well.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
