[soc-camera] about the y_skip_top parameter

[Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>]

Hi all,

The y_skip_top parameter tells the cameras to effectively make the
picture one line higher. I think this parameter was introduced to work
around a bug in the pxa camera interface. The pxa refuses to read the
first line of a picture. The problem with this parameter is that it is
set to 1 in the sensor drivers and not in the pxa driver, so it's the
sensor drivers which work around a bug in the pxa. On other
hardware platforms (mx27 in this particular case) I cannot skip the
first line, so I think this parameter should be set to 1 in the pxa
driver and not the sensor drivers.

What do you think?

Sascha
