Hi Gilles,
If you want to write a driver for blackfin, you can visit
http://blackfin.uclinux.org/ and find linux kernel repo url.
I have written a blackfin bridge driver, vs6624 sensor driver and
adv7183 decoder driver. You can reference vs6624 driver.

Hi guys,
I find an issue about the USB TV tuner, WinTV HVR950, which use em28xx

The two recently added ioctl()s VIDIOC_CREATE_BUFS and VIDIOC_PREPARE_BUF
allow user-space applications to allocate video buffers of different
sizes and hand them over to the driver for fast switching between
different frame formats. This patch adds support for buffers of different

Prepare the sh_mobile_ceu_camera friver to support the new
VIDIOC_CREATE_BUFS and VIDIOC_PREPARE_BUF ioctl()s. The .queue_setup()
vb2 operation must be able to handle buffer sizes, provided by the

This patch set is now trying to implement our most recent decisions. Any
improvements should be doable as incremental patches. As long as we are
happy with ioctl()s themselves, the rest can be improved. I'll quote my
earlier email with our strategic design decisions:
1. VIDIOC_CREATE_BUFS passe
A possibility to preallocate and initialise buffers of different sizes
in V4L2 is required for an efficient implementation of a snapshot
mode. This patch adds two new ioctl()s: VIDIOC_CREATE_BUFS and
VIDIOC_PREPARE_BUF and defines respective data structures.

MAPPED flag was set for the buffer only if all it's planes were mapped and
relied on a simple mapping counter. This assumption is really bogus,
especially because the buffers may be mapped multiple times. Also the
meaning of this flag for muliplane buffers was not really useful. This
