Subject: [PATCH v6 03/13] dt-bindings: add bindings for DE2 on V3s SoC
Date: Thu, 4 May 2017 19:48:48 +0800 [thread overview]
Message-ID: <20170504114858.9008-4-icenowy@aosc.io> (raw)
In-Reply-To: <20170504114858.9008-1-icenowy@aosc.io>
Allwinner V3s SoC have a display engine which have a different pipeline
with older SoCs.
Add document for it (new compatibles and the new "mixer" part).
Signed-off-by: Icenowy Zheng <icenowy@aosc.io>
Acked-by: Rob Herring <robh@kernel.org>
---
Changes in v4:
- Removed the refactor at TCON chapter.
Changes in v3:
- Remove the description of having a BE directly as allwinner,pipeline.
