From fc30dd7647e502b757c47c2a1b7163face9e0272 Mon Sep 17 00:00:00 2001 From: Olli Salonen Date: Mon, 24 Nov 2014 03:57:34 -0300 Subject: [PATCH] [media] em28xx: Add support for Terratec Cinergy T2 Stick HD Terratec Cinergy T2 Stick HD [eb1a:8179] is a USB DVB-T/T2/C tuner that contains following components: * Empia EM28178 USB bridge * Silicon Labs Si2168-A30 demodulator * Silicon Labs Si2146-A10 tuner I don't have the remote, so the RC_MAP is a best guess based on the pictures of the remote controllers and other supported Terratec devices with a similar remote.
