From: "Igor M. Liplianin" <liplianin@...by>
To: <mchehab@...radead.org>, <linux-media@...r.kernel.org>,
<linux-kernel@...r.kernel.org>
Subject: [PATCH 05/18] Initial commit to support NetUP Dual DVB-T/C CI RF card.
The card based on cx23885 PCI-e brige. Altera FPGA for CI,
multistandard demods stv0367 from STM for QAM & OFDM, Xcieve xc5000 tuners
and additional cx25840 for second analog input.
Signed-off-by: Igor M. Liplianin <liplianin@...up.ru>
