Adds support for setting a SD mode from HD mode correctly. Also the transparency
ioctl now has a struct instead of a integer value, allowing disable/enabling
full plane transparency and also for setting the transparent level (from 1/8 to
8/8). This patch also removes unused code and trailing whitespaces

This patch normalizes the v4l2_input structs using the same definitions on
the header file and the source. Also avoid a segfault when memcopying the
struct on ioctl ENUMINPUT

For some reason the v4l2_input struct had different sizes on user space and
kernel space, adding this attribute makes the struct to have the same size
on both userspace and kernel and will make the ioctl to have the same number
now.

* Make the logo appear again, there's still some bug on the colors, but is a
  start
* Fix the initial mode setting, some value wasnt set, so the initial mode
  was never ok
* Still some bug when returning to SD mode from HD mode

add 576p and 720p adc configure, set the vpfe max buffer
size to 1920x1080

This patch cleans up the code, renames function to the same scheme, adds
support for 1080i and fixes some offsets on the screen.

add progressive buffer logic to vpfe buffer system,
support dynamic choose the input port,
support ccdc configure for component input port,
add some component standard for v4l2 interface

Adds the LED devices and set the PINMUX0 to be GPIO's, so we can use them
for the LEDS.

For the ntosd_644xa machine, we disable the VLYNQ and AEAW mux to use the pins
as GPIOS.

There are several subsystems in the kernel that just include this file in
order to support gpio drivers, make this header include by itself the needed
headers to avoid errors at compilation

Improve input selection in OSS driver. add ioctl() support.

This makes the new framebuffer driver to be selected and removes the old
davincifb.

This will fix unresolved symbols errors when the video output control option
is not selected.

This patch afixes several driver bugs
* Make the windows disabled by default at module load and unload
* Enable the attribute window
* Change the order of the windows, now osd0 is fb0, so the video mode change
  must be done on vid0 which is fb1
* Remove more unsued code
* Make the enable_digital output to not change the window configurations
* Add a new ioctl to enable color bar test mode
* Fix some of the rules of the check_var function, now the virtual size of the
  window is handled automatic based on the 32 bytes align constraints

This adds more memory to the attribute window, to make it big enough for
a 720x480 screen, this is enough for now.

Remove the logic of auto detect on valid input signal.
Let user decide choose and decide which one is valid.

To avoid waste time on needless hwif probe, add logic for wait_hwif_ready
function: if all drives in a HW interface was marked as "noprobe", then
skip the HW interface probe.

There are two port of composite input, can select which one input.

Remove all OR'ed return values, this mades the driver to work on vlc. Now the
driver is more standard.

device driver must register class device, or the mdev(udev) can not
get enough message to create the device node

the previous way will clear all pins signal when
set any thing to the clear register

Lots of new stuff has been addded, here is a brief summary:
* New ioctl to set transparency color
* New ioctl to enable transparency on osd0 and osd1
* The memory allocation now is provided by a struct on the machine description
  Basically, it tells how big the buffers for every plane should be
* Clean up the code, remove unusued code
* Add support for mode switching on vid0 plane, SD / HD is supported, the
  latter is not tested
* Add support for mode list, you can list the modes with:
  cat /sys/class/graphics/fb0/modes
* Add support for mode set, you can se the mode with:
  echo MODE > /sys/class/grpahics/mode
  where MODE is one of the returned my the previous command
* Output switch works, by writing the enum value found on davincifb.h
  to /sys/class/video_output/venc
