Subject: Re: [PATCH V3.6 2/2] linux-media: dvbsky: add support for Mygica T230C v2
Date: Wed, 17 Jul 2019 20:11:50 +0200	[thread overview]
Message-ID: <20190717181150.GB5495@jpvw.nl> (raw)
In-Reply-To: <20190717180544.GA5356@jpvw.nl>

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.
