- This is a video4linux driver for Telegent tlg2300 based TV cards.
- The driver supports V4L2, DVB-T and radio.
-
- This driver is deprecated and will be removed soon. If you have
- hardware for this and you want to work on this driver, then contact
- the linux-media mailinglist.
-
- To compile this driver as a module, choose M here: the
- module will be called poseidon
