[linux-sunxi] [PATCH 07/13] ARM: sun8i: h3: add display engine pipeline barebone

[jernej.skrabec@siol.net (Jernej Škrabec)]

Hi Icenowy,

Dne torek, 01. avgust 2017 ob 15:12:58 CEST je Icenowy Zheng napisal(a):
> As we have already the support for the DE2 on Allwinner H3, add the
> display engine pipeline device tree nodes to its DTSI file.
> 
> The H5 pipeline has some differences and will be enabled later.
