From 82c10276d4e86fa51b89cf62a1cf6ed12d543843 Mon Sep 17 00:00:00 2001 From: Olli Salonen Date: Mon, 29 Sep 2014 04:44:16 -0300 Subject: [PATCH] [media] cx23855: add support for DVBSky T980C (no CI support) This patch adds basic support for DVBSky T980C card. CI interface is not supported. DVBSky T980C is a PCIe card with the following components: - CX23885 PCIe bridge - Si2168-A20 demodulator - Si2158-A20 tuner - CIMaX SP2 CI chip The demodulator and tuner need firmware. They're the same as used with TT CT2-4650 CI: https://www.mail-archive.com/linux-media@vger.kernel.org/msg78033.html Signed-off-by: Olli Salonen Reviewed-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab --- drivers/media/pci/cx23885/cx23885-cards.c | 40 +++++++++++++++ drivers/media/pci/cx23885/cx23885-dvb.c | 61 +++++++++++++++++++++++ drivers/media/pci/cx23885/cx23885.h | 1 + 3 files changed, 102 insertions(+) diff --git a/drivers/media/pci/cx23885/cx23885-cards.c b/drivers/media/pci/cx23885/cx23885-cards.c index 88c257d1161b..e8965e63eb09 100644 --- a/drivers/media/pci/cx23885/cx23885-cards.c +++ b/drivers/media/pci/cx23885/cx23885-cards.c @@ -680,6 +680,10 @@ struct cx23885_board cx23885_boards[] = { .portb = CX23885_MPEG_DVB, .portc = CX23885_MPEG_DVB, }, + [CX23885_BOARD_DVBSKY_T980C] = { + .name = "DVBSky T980C", + .portb = CX23885_MPEG_DVB, + }, };
