Sean Paul d02cf0a4f4 drm/i915: Make use of indexed write GMBUS feature
This patch enables the indexed write feature of the GMBUS to concatenate
2 consecutive messages into one. The criteria for an indexed write is
that both messages are writes, the first is length == 1, and the second
is length > 0. The first message is sent out by the GMBUS as the slave
command, and the second one is sent via the GMBUS FIFO as usual.

Changes in v3:
- Added to series
Changes in v4:
- Combine indexed reads and writes (Ville)
Changes in v5:
- checkpatch whitespace nits
Changes in v6:
- None

============

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.
