From: Jan Pieter van Woerkom <jp@xxxxxxx> Adds support for the "Mygica T230C v2" into the "dvbsky" driver. A small enhancement is also needed in the si2168 demodulator driver, and a USB device ID in dvb-usb-ids.h . This is v3.3 of the proposed patch, based on feedback from Sean Young and Antti Palosaari. Tested by patch author on a T230C v2. Tested by Frank Rysanek on a T230C v2: can tune into locally available DVB-T and DVB-T2 muxes, video and audio playback works. Applies cleanly against Linux 5.1.10 . The T230C v2 hardware needs a mode of the si2168 chip to be set for which the si2168 driver previously had no support. This patch uses a specific measure to configure this on the T230C v2 hardware only - see the flag passed via the ts_mode attribute and its dependency on USB_PID_MYGICA_T230C2. Other devices using the si2168 demodulator driver are not affected in any way.
