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 v4 of the proposed patch, based on feedback from Sean
Young and Antti Palosaari.
Tested by patch author: can tune into DVB-(T/T2/C) muxes, AV
playback & data all work.
Tested by Frank Rysanek: can tune into locally available DVB-T
and DVB-T2 muxes, video and audio playback works.
Applies cleanly against Linux 5.1.* .
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_clk_special attribute and
its dependency on USB_PID_MYGICA_T230C2. Other devices using the
si2168 demodulator driver are not affected in any way.
