Tons of cirrus logic docs:
ftp://ftp.leo.org/pub/comp/general/devices/cirruslogic/pubs
They've got tech refs, etc.. (gd5446trm.pdf.gz, ...)

There's a user space driver (no v4l) at:
http://users.actcom.co.il/~nahshon/linux-tv.html
It supports gd5446, gd5465, gd5480 and the CL-PX4072 pixel decoder.
I have an lgv-5480tvr card which uses gd5480, vpx3225d, and Samsung
TCPN9082DA27C NTSC tuner. A small patch to his driver got the card working
(assumes vpx3225d will only be used in NTSC mode).
The driver/program only supports overlay, no capture.
