From 8bb09db375fe4f15d16315947500e827caa0fe9c Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Tue, 9 Jun 2009 20:47:21 -0300 Subject: [PATCH] V4L/DVB (11951): cx18: Add DVB-T support for the Leadtek WinFast DVR3100 H This adds support for DVB-T on the Leadtek DVR3100 H and should also get analog TV capture from the tuner working properly as well. DVB-T 6 MHz and 8 MHz have been tested and verified to work by Terry Wu of Leadtek. DVB-T 7 MHz has also been verified working with a change developed by Terry to the tuner-xc2028.c driver. Special thanks go to Terry Wu of Leadtek who provided the needed information and testing to get digital TV working for the Leadtek DVR3100 H.
