Date: Thu, 30 Jul 2015 18:08:58 +0100 Message-Id: <1438276141-16902-9-git-send-email-peter.griffin@linaro.org> X-Mailer: git-send-email 1.9.1 In-Reply-To: <1438276141-16902-1-git-send-email-peter.griffin@linaro.org> References: <1438276141-16902-1-git-send-email-peter.griffin@linaro.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 9081 Lines: 299 This patch adds support for the following 2 NIM cards: - 1) B2100A (2x stv0367 demods & 2x NXP tda18212 tuners) 2) STV0903-6110NIM (stv0903 demod + 6110 tuner, lnb24) A NIM card is a cold plugable expansion card which usually features a demodulator / tuner combination.
