Subject: [PATCH 3/3] dt-bindings: media: ov772x: Document endpoint props
Date: Tue, 18 Aug 2020 14:20:12 +0200 [thread overview]
Message-ID: <20200818122012.37956-4-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20200818122012.37956-1-jacopo+renesas@jmondi.org>
Document endpoint properties for the parallel bus type and
add them to the example.
Specify a few constraints:
- If the bus type is BT.656 no hsync or vsycn polarities can be
specified.
- If the bus width is 10 bits, not data-shift can be applied.
