From f35a6467b74ef21874ce7aee3bc2728fbb22742c Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sat, 9 Aug 2008 11:23:15 -0400 Subject: cxusb: add support for DViCO FusionHDTV DVB-T Dual Digital 4 (rev 2) From: Anton Blanchard Add support for revision 2 of the DViCO FusionHDTV DVB-T Dual Digital 4 which has new tuners and demodulators (2 x DIB7070p). With this patch both DVB reception and IR works. The dib7000p driver currently hardwires the output mode to OUTMODE_MPEG2_SERIAL regardless of what we ask for. Modify it to allow OUTMODE_MPEG2_PAR_GATED_CLK to be set. Longer term we should remove the check completely and set the output mode correctly in all the callers. Add Kconfig bits to ensure the dib7000p and dib0070 modules are enabled. It would be nice to only do this for the !DVB_FE_CUSTOMISE case, but this is what the other DIB7070 module does (there are a number of module dependencies in the attach code).

DMB-TH is the HDTV broadcast standard used in Hong Kong and China. [...] I've also attached a second patch against the dvb-apps repository which adds a DMB-TH scan file for Hong Kong.
