CX25840/1/2/3 datasheet:
http://dl.ivtvdriver.org/datasheets/video/cx25840.pdf

V4L2 framework for drivers to use:
http://git.linuxtv.org/media_tree.git/blob/HEAD:/Documentation/video4linux/v4l2-framework.txt

V4L2 kernel-userspace API:
http://linuxtv.org/downloads/v4l-dvb-apis/

Videobuf2 kernel internal subsystem (to help with implementing V4L2
API):
http://lwn.net/Articles/447435/

Note:
1. the CX2584x chip has a lot of features to program
2. the V4L2 API is large and has a lot of requirements to implement
3. If you only implement SECAM-D/K at first, think ahead on how to
support other TV standards later.

Andy
