Let the driver use 4 instead of 3 predefined DMA buffers. This circumvents the calling of broken buffer_setup/buffer_release functions.

Enable the stretching of the video planes to fix the pixel aspect ratio on
NTSC/PAL output formats. The hw constraints have been adapted to the video
encoder sizes instead of the fb logical sizes.

This patch uses the ping-pong buffer feature of the OSD to fix the inverted
issue.

This patch moves the output display on 720p mode 16 pixels to the left.

Adding the vid0 plane fix, makes the display refresh to be too slow. With this
patch the fix is disabled.

This fixes the bug found on 1.3 hw revision. Basically the bug is found when
the video out is in interlaced mode, vid0 picks up the inverted field order
(even when should be odd and vice versa), to avoid that we use the ping-pong
feature of the vid0 plane to swap the order on every interrupt.

When O_NONBLOCK is specified, try to lock the mutex and return immediately
if it failed (because another process has opened it for example)

this change fix the video jump at the beginning after
configure tvp7000

This patch run a software reset before start to program the
registers. it's also used to allow full reset of the audio
settings on soft reboot.

CODEC_CLKIN and PLLCLK_IN register are not initialized and
PLL Q,P,J,D value are wrong, cause audio clock is wrong.
This patch initialize PLLCLK_IN uses MCLK, Codec uses PLLDIV_OUT.

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.
