[PATCH 0/4] Add SimpleFB support for Allwinner H3 SoC

[PATCH 0/4] Add SimpleFB support for Allwinner H3 SoC

[Icenowy Zheng]

This patchset adds devicetree-side support of SimpleFB on Allwinner H3
SoC.

The DE2 CCU is initialized and used by the SimpleFB node, in order to
furtherly coexist with the DRM code.

The first patch adds pipelines for DE2 displays in simplefb-sunxi
device tree binding.

The second patch adds DE2 CCU device node for H3 SoC, and the skeleton
of the node enters the H3/H5 common DTSI; the H5 support is splited
into the third patch, as they will enter different tree.

The fourth patch finally adds simplefb nodes, using the
pipeline strings introduced in the first patch.

Icenowy Zheng (4):
  dt-bindings: simplefb-sunxi: add pipelines for DE2
  ARM: sun8i: h3/h5: add DE2 CCU device node for H3
  arm64: allwinner: h5: add compatible string for DE2 CCU
  ARM: sunxi: h3/h5: add simplefb nodes

The DE2 in H3/H5 has a clock control unit in it, and the behavior is
slightly different between H3 and H5.

Add the common parts in H3/H5 DTSI, and add the compatible string in H3
DTSI.

The compatible string of H5 DE2 CCU will be added in a separated patch.

I don't know device tree very well, but shouldn't this node be
disabled so that it doesn't do anything weird on H5? Or are nodes
without compatibles ignored?

This is what I get for reviewing before reading the full patch set.

Shouldn't this be rolled into the previous patch?

as the U-Boot side is applied to u-boot-video, could you take a look at

Sorry, this compatible is wrong.

Please wait for my new version of this patchset to add a
allwinner,sun8i-h3-de2-clk and use it.
