V4L/DVB (5954): Sync with DiBcom Driver Release 2.1.3 + some improvements
This changesets syncs the OpenSource driver for DiBcom demodulators with version 2.1.3 of DiBcom reference driver. There were some improvements since the last release for linux-dvb, e.g.: - stepped AGC startup - less space for initialization - diversity synchronization Furthermore this changeset contains the following things: - latest AGC settings for MT2266-based devices (namely Nova-TD and other) will improve the sensitivity - support for STK7700D reference design in dib0700-devices - remove some line-breaks when debugging is enabled - getting rid of layer between frontend_parameters and ofdm_channel used in dib*-drivers Signed-off-by: Patrick Boettcher <pboettcher@dibcom.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
