Subject: [RFC PATCH 01/11] dt-bindings: update the binding for Allwinner H3 TVE support
Date: Thu, 18 May 2017 00:43:44 +0800 [thread overview]
Message-ID: <20170517164354.16399-2-icenowy@aosc.io> (raw)
In-Reply-To: <20170517164354.16399-1-icenowy@aosc.io>
Allwinner H3 features a "DE2.0" and a TV Encoder.
Add device tree bindings for the following parts:
- H3 TCONs
- H3 Mixers
- The connection between H3 TCONs and H3 Mixers
- H3 TV Encoder
- H3 Display engine
