Subject: [PATCH 02/13] v4l2: add RF gain control
Date: Wed, 2 Sep 2015 00:59:18 +0300 [thread overview]
Message-ID: <1441144769-29211-3-git-send-email-crope@iki.fi> (raw)
In-Reply-To: <1441144769-29211-1-git-send-email-crope@iki.fi>
Add new RF tuner gain control named RF Gain. That is aimed for first
amplifier chip right after antenna connector.
There is existing LNA Gain control, which is quite same, but it is
aimed for cases amplifier is integrated to tuner chip. Some designs
have both, as almost all recent tuner silicons has integrated LNA/RF
amplifier in any case.
