Subject[PATCH 2/3] media: dt-bindings: media: i2c: Add bindings for TW9900
Date
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.
