Instead of using ill-defined numbers (0, 1, and 2) for the monitor port, allow
the user to specify the port by name ("dvi", "lvds", or "dlvds"). This works
on the kernel command line, the module command-line, and the sysfs "monitor"
device.
Note that changing the monitor port does not currently work on the P1022DS,
because the code that talks to the PIXIS FPGA is broken.

An upcoming SoC of TI comes with an LCD controller which is an updated
version of that found on TI's DA850 SoC. The da8xx-fb driver can support
this LCD with some enhancements.
This patch adds support for updated interrupt configuration on the new
SoC.
1) Registers for setting and clearing interrupts are different.
2) Raw and masked status registers are different.
The updates have been tested on an emulation platform for new features
and the patch has been tested on DA850 platform to make sure nothing
existing breaks.

Match udlfb only against vendor-specific class (e.g. only DisplayLink
graphics, not composite standard audio class interfaces). This enables
compatibility with composite graphics+audio devices (e.g. HDMI).
Match udlfb only against compatible subclass 0 and protocol 0 chips.
DisplayLink's USB 3.0 generation chips increment these values
to signal that they have a incompatible protocol, preventing udlfb
from erroneously matching to hardware it does not support.
Tested to confirm proper behavior on both USB 2.0 and USB 3.0
generation devices.

The third parameter of module_param is supposed to be an octal value.
The missing leading "0" causes the following:
$ ls -l /sys/module/carminefb/parameters/
total 0
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_displays
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_mode
-rw-rwxr-- 1 root root 4096 Jul 8 08:55 fb_mode_str
After fixing the perm parameter, we get the expected:
$ ls -l /sys/module/carminefb/parameters/
total 0
-r--r--r-- 1 root root 4096 Jul 8 08:56 fb_displays
-r--r--r-- 1 root root 4096 Jul 8 08:56 fb_mode

The Freescale DIU framebuffer driver defines two constants, MIN_PIX_CLK and
MAX_PIX_CLK, that are supposed to represent the lower and upper limits of
the pixel clock. These values, however, are true only for one platform
clock rate (533MHz) and only for the MPC8610. So the actual range for
the pixel clock is chip-specific, which means the current values are almost
always wrong. The chance of an out-of-range pixel clock being used are also
remote.
Rather than try to detect an out-of-range clock in the DIU driver, we depend
on the board-specific pixel clock function (e.g. p1022ds_set_pixel_clock)
to clamp the pixel clock to a supported value.

The situation in which the problem occurred was with a Plugable UGA-2K-A
connected to a Samsung EX2220X display. The driver indicates that
1920x1080 is a valid mode (the first mode available, in fact), but
proceeds to set the framebuffer size to 1600x1200.
The patch corrects what seems to be a logic error, regarding unsetting
the FB_MISC_1ST_DETAIL flag, if the first (top/best) mode is invalid.
The existing code unset the flag if ANY mode was invalid.

The function sm501fb_init_fb() references
the variable __devinitdata sm501_default_mode.
This is often because sm501fb_init_fb lacks a __devinitdata
