From 11a2a949d05e9d2d9823f0c45fa476743d9e462b Mon Sep 17 00:00:00 2001 From: Olli Salonen Date: Mon, 4 Apr 2016 12:12:52 -0300 Subject: [media] em28xx: add support for Hauppauge WinTV-dualHD DVB tuner Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with following components: USB bridge: Empia EM28274 (chip id is the same as EM28174) Demodulator: 2x Silicon Labs Si2168-B40 Tuner: 2x Silicon Labs Si2157-A30 This patch adds support only for the first tuner. The demodulator needs firmware, available for example here: http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/ The demodulators sit on the same I2C bus and their addresses are 0x64 and 0x67. The tuners are behind the demodulators and their addresses are 0x60 and 0x63.
