Hauppauge 9x5 devices, such as HVR-935, HVR-955Q, and HVR-975
have moved from cx231xx usb bridge to Empia em2828x bridge.
This series depends on my previous series:
em28xx: Add empia EM2828X chip
The new devices have all capabilities as previous generation.
- 935 - DVB-T/T2/C, analog tv, composite, s-video, stereo audio
- 955 - QAM/ATSC, analog tv, composite, s-video, stereo audio
- 975 - DVB-T/T2/C + QAM/ATSC, analog tv, composite, s-video, stereo audio
DVB demod: si2168
ATSC demod: lgdt3306a
tuner: si2177
The em28xx driver needed to be expanded slightly to accommodate
a second i2c client frontend, it already was setup for "old"
style multi frontend use already.
The si2177 tuner chip puts out decoded CVBS video, and therefore
requires additional configuration when setting up analog tuning parameters.
Regards,
Bradford

Capabilities are: - Digital TV - Composite video input - S-Video input - Analog stereo input HVR-955 has ATSC/QAM demod (si2168). HVR-935 has DVB-C/T/T2 demod (lgdt3306a). HVR-975 has both ATSC/QAM and DVB-C/T/T2 demods.

The following USB device id's are new: 2040:0360 - HVR-935 ISOC transport 2040:8360 - HVR-935 Bulk transport 2040:0366 - HVR-955 ISOC transport 2040:8366 - HVR-955 Bulk transport 2040:036a - HVR-975 ISOC transport 2040:836a - HVR-975 Bulk transport The devices all now utilize si2177 tuner. Capabilities are: - Digital TV - Composite video input - S-Video input - Analog stereo input HVR-935 has DVB-C/T/T2 demod (si2168). HVR-955 has ATSC/QAM demod (lgdt3306a). HVR-975 has both ATSC/QAM and DVB-C/T/T2 demods.

This series depends on my previous series: media: em28xx: Add support for Empia em2828X bridge The following USB device id's are new: 2040:0360 - HVR-935 ISOC transport 2040:8360 - HVR-935 Bulk transport 2040:0366 - HVR-955 ISOC transport 2040:8366 - HVR-955 Bulk transport 2040:036a - HVR-975 ISOC transport 2040:836a - HVR-975 Bulk transport The new devices have all capabilities as previous generation. - 935 - DVB-T/T2/C, analog tv, composite, s-video, stereo audio - 955 - QAM/ATSC, analog tv, composite, s-video, stereo audio - 975 - DVB-T/T2/C + QAM/ATSC, analog tv, composite, s-video, stereo audio DVB demod: si2168 ATSC demod: lgdt3306a tuner: si2177 The em28xx driver needed to be expanded slightly to accommodate a second i2c client frontend, it already was setup for "old" style multi frontend use already. The si2177 tuner chip puts out decoded CVBS video, and therefore requires additional configuration when setting up analog tuning parameters. --- Changes since v1: - Renamed some variables - Fixed some comments - Explicitly added USB id's affected Regards, Bradford Bradford Love (3): em28xx: driver supports two frontends, but not i2c clients si2157: Include support for si2177 chip em28xx: Add Hauppauge em2828X based 9x5 revisions drivers/media/tuners/si2157.c | 208 +++++++++++++---- drivers/media/tuners/si2157_priv.h | 3 +- drivers/media/usb/em28xx/em28xx-cards.c | 157 +++++++++++++ drivers/media/usb/em28xx/em28xx-dvb.c | 284 ++++++++++++++++++++---- drivers/media/usb/em28xx/em28xx-video.c | 22 +- drivers/media/usb/em28xx/em28xx.h | 3 + 6 files changed, 588 insertions(+), 89 deletions(-) -- 2.35.1 ^ permalink raw reply [flat|nested] 8+ messages in thread
