From aeb012bbf460171b75ba17dc064a543f7256521f Mon Sep 17 00:00:00 2001 From: Chris Pascoe Date: Mon, 19 Nov 2007 21:57:10 -0300 Subject: V4L/DVB (6649): Add support for the DViCO FusionHDTV Dual Digital 4 Add support for DViCO's Dual Digital 4 with xc3028 tuner, zl10353 DVB-T demodulator and a new-style I2C IR remote control receiver. This would not have been possible without the work of and advice from Mike Krufky, who originally got the Dual Digital 4 and second-gen DVB-T NANO devices working with the out-of-tree XC3028 driver. I converted it to use the in-tree XC3028 driver (after making it suitable for our use), and added the IR remote control support based on his advice. NB: a firmware package is required to use this device.
