commit babf51f887554743a46a5078832fe4013f02a018

Removing via_dp_* functions
Removing via_dp_* functions inside via_outputs.c. These functions are
not really doing anything useful, so they will be deleted. Apparently,
they were originally meant for CX700, VX800, VX855, and VX900 chipsets.
via_lvds_* functions are already handling integrated TMDS and LVDS
transmitters for the above chipsets.

Fixing header file compilation errors with an older version gcc
It was observed with an older version gcc where including xf86Crtc.h and
xf86fbman.h inside via_ums.c causes compilation errors. It appears that
via_driver.h includes necessary header files to correctly compile ums.c,
therefore, xf86Crtc.h and xf86fbman.h will no longer be explicitly included
inside via_ums.c.

Fixing the misdetection of NanoBook flat panel
It was observed in a VIA Technologies NanoBook based laptop computer
that the flat panel it contains is not connected to an I2C bus, hence
the supported screen resolution cannot be determined via an I2C bus.
Furthermore, the code was obtaining EDID information via I2C bus 2, but
it was not scrutinizing the interface type. Hence, if a VGA monitor
is connected to the computer, the code was determining the flat panel
screen resolution based on the EDID information obtained from the VGA
monitor via I2C bus 2. Due to all of these issues, the flat panel
screen color was going completely white, making the flat panel
completely useless. Thanks to this fix, the flat panel and a VGA
monitor can now be detected correctly.

commit 7a98f6584fec8dd7d6f516d6718839b5c96342cc
Author: Kevin Brace <kevinbr...@gmx.com>
Date: Sat Mar 5 11:33:08 2016 -0800
Using I2C bus 2 to detect a VGA monitor
Previously, it was assumed that I2C bus 1 is used to detect only a VGA
monitor. It was also assumed that I2C bus 2 is used to detect a DVI
monitor or TV encoder. However, for devices with a DVI-I connector,
VGA signals come out of the connector as well. What this means is that
I2C bus 2 also has to be used to detect a VGA monitor, in addition to
I2C bus 1. Furthermore, EDID obtained from the monitor via I2C bus
will be used to determine whether or not it is an analog type
(i.e., VGA monitor).
