Subject: [PATCH v3 2/3] media: dt-bindings: media: i2c: Add bindings for TW9900
Date: Tue, 22 Dec 2020 17:04:06 +0100	[thread overview]
Message-ID: <20201222160407.501586-3-maxime.chevallier@bootlin.com> (raw)
In-Reply-To: <20201222160407.501586-1-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.

Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com>

V2->V3 : Fix the example not compiling due to a typo in the reset-gpios
node.
