Subject: [PATCH 2/3] media: dt-bindings: media: i2c: Add bindings for TW9900
Date: Fri, 18 Sep 2020 16:24:21 +0200 [thread overview]
Message-ID: <20200918142422.1086555-3-maxime.chevallier@bootlin.com> (raw)
In-Reply-To: <20200918142422.1086555-1-maxime.chevallier@bootlin.com>
The Techwell TW9900 is a video decoder supporting multiple input
standards, such as PAL, NTSC and SECAM, and outputs a BT.656 video
signal.
It's designed to be low-power, posesses some features such as a
programmable comb-filter, and automatic input standard detection.
