Subject: [PATCH] media: si2168: add support for Mygica T230C v2
commit bc28d36bf11acc5b7bbd1a6ffbe315d15e7c0d0d upstream.
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.
