Subject: [PATCH v9 10/13] media: dt-bindings: tvp5150: cleanup bindings stlye
Date: Thu, 22 Aug 2019 10:05:53 +0200	[thread overview]
Message-ID: <20190822080556.17109-11-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20190822080556.17109-1-m.felsch@pengutronix.de>

Use underlines to highlight optional and required properties. This is
quite common for all bindings. Align descriptions and start sentence
with uppercase letter. Also reword the usage of the required
endpoint properties for the output port in case BT.656 should be used.
