This patchset tries to implement the Allwinner A64 DE2 as a bus driver,
in order to model the fact that the SRAM claim controls the access to
the whole DE2 memory space.
PATCH 1 and PATCH 4 are for the CCU part.
PATCH 2 is the device tree binding for the A64 DE2 bus, and PATCH 3
implements the bus driver.
PATCH 5 adds the DE2 CCU device tree node, with the DE2 bus node.
PATCH 6 and 7 are HDMI simplefb patches for A64. They're present as a
test to this patchset.
Icenowy Zheng (7):
dt-bindings: add compatible string for the A64 DE2 CCU
dt-bindings: add binding for the Allwinner A64 DE2 bus
bus: add bus driver for accessing Allwinner A64 DE2
clk: sunxi-ng: add A64 compatible string
arm64: allwinner: a64: add necessary device tree nodes for DE2 CCU
arm64: allwinner: a64: add device tree node for HDMI simplefb
arm64: allwinner: a64: add HDMI regulator to all DTs' simplefb_hdmi

The Allwinner A64 SoC has a DE2 CCU like the one in the DE2 of Allwinner
H5 SoC.
Add a compatible string for it.

Apart from the (minor) comments I made that can be fixed up while
applying, I'm happy with those changes. I'd still like to get a review
from Rob, so I'll wait for it to apply them.
Thanks a lot for working on this,
Maxime

Applied all the patches with the minor modifications Chen-Yu and I
suggested.
The threading was broken on your serie though, so you probably want to
check your git configuration.
Thanks!

In fact I think I should check my ISP configuration.
The breakage is introduced due to too long delay between aosc.io
mail server and my computer, so I must start to send the
remaining patches again.
