After some tedious work with a logic probe and a magnifying glass, I've
determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz
IF output on pin 12 and the FM 10.7MHz If output on pin 11.  GPIO 2 is used to
switch the card's analog sound output from from the analog input connector to
the CX23883's audio DACs.

So, in radio mode GPIO2 = 1 and GPIO7 = 0.

Add some comments about how the HD-3000's GPIOs are connected.

Delete the vmux setting for the radio, as vmux doesn't apply to radio mode.
Also delete the lines setting unused gpio words to zero; it's not necessary as
0 is the default value for uninitialized fields.

In the current driver, the field order is global. As soon as it's changed it
takes immediate effect. This is a problem when the video changes order mid
stream. Although it mostly works okay, the video may judder / flicker.

This patch attaches the field order to the frame, so that any buffered frames
will not be displayed until the correct field. In the event that the field
order is changed mid stream, the driver will ensure that the previous frame
is displayed for a minimum of 3 fields. These are the two original fields the
frame should have occupied, plus the one extra since the new frame still has
to wait for the correct field.

The yuv output code always compares the new frame position & size with those
of the previous frame. If they are different, a flag is set to request the
yuv output registers be updated when the new frame is displayed.

If the incoming frames are delivered too fast, exhausting the buffers, the
most recent frame already buffered will be discarded. Unfortunately, any
update request will also be discarded. If the new frame matches the size &
position of the now discarded frame, the yuv registers are not flagged for
update & will remain in their old state.

This patch preserves the register update flag in the event that a frame is
dropped.

Framebuffer timings are currently locked to the video format in use when the

When the video standard is changed, there's no guarantee the framebuffer
dimensions are still legal. The yuv output code uses these dimensions to
calculate the size & position for the video overlay. If the framebuffer
dimensions are now illegal, the output may exceed the vertical limit of the
display, causing distortion.

This patch adds an additional check to ensure the output doesn't exceed
the limits for the current video standard, cropping if required.

Change the video_nr parameter to an array, so that the video number can be
specified when a user has more than one card.  The driver would try to give
all cards the same number otherwise, which will fail for all cards after the

The default_input option would only allow values of 0 or 1, contrary to the

Debugging cleanups to the zr36067 driver:

* Use module_param_named() to declare the debug parameter, so we can
  use a single global variable to handle the debug level. This makes
  the driver a bit smaller (by 648 bytes on x86_64), thanks to one
  less level of indirection on every use.

* Change the debug parameter sysfs permissions, so that the debug
  level can be adjusted at runtime, as is done in many other
  media/video drivers.

* The debug level is between 0 and 5, not 0 and 4.

* Move the zr_debug export and dprintk macro definition to a header
  file so that we don't have to define them in each source file.

* Simplify a duplicate test on zr_debug.

Note that zr_debug was subsequently renamed to debug_zr36067 to avoid
possible conflicts with other Zoran device drivers, on a suggestion
by Trent Piepho.

Right now the composite sound input doesn't work on AverTV 307 because of
