Hi,
I've managed to make my TechnoTrend TT-connect S2-3650 CI work using the
pctv452e driver from s2-lipianin on 2.6.35.10. It runs fine (both
regular and HD channels), but there are some minor issues:
- vdr-femon always reports a very low signal strenght (between 0 and
2%), I guess the driver is
While attempting to build recently I have found the 'make distclean'
target fails if 'rm' tries to remove a file that is not there. The
attached patch fixes the issue for me (by using rm -f).
I converted all the other 'rm' calls to 'rm -f' along the way.
Please consider applying this.
Cheers
'make tar' fails for me (building against ubuntu 2.6.32) unless I
remove videodev.h from TARFILES.
Is this the correct thing to do here?

Hi Jon, Laurent,
This patch series converts the OLPC cafe_ccic driver to the new control
framework. It turned out that this depended on the removal of the legacy
s_config subdev operation. I originally created the ov7670 controls in
s_config, but it turned out that s_config is called after
Drivers can use the has_new field to determine if a new value was specified
for a control. The v4l2_ctrl_handler_setup() must always set this to 1 since
the setup has to force a full update of all controls.

The core.s_config op was meant for legacy drivers that needed to work with old
pre-2.6.26 kernels. This is no longer relevant. Unfortunately, this op was
incorrectly called from several drivers.
Replace those occurences with proper i2c_board_info structs and call
v4l2_i2c_new_subdev_board.
After
Some subdevs need to call into the board code after they are registered
and have a valid struct v4l2_device pointer. The s_config op was abused
for this, but now that it is removed we need a cleaner way of solving this.
So this patch adds a struct with internal ops that the v4l2 core can call.
And also swapped the out_free and out_unreg labels as they were in the
wrong order.
Tested with the OLPC laptop.

E.g. the same check in userspace (var 0). If var has changed the sign
