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 is a modified version of A64 DE2 CCU patch, which uses the A64
DE2 bus.

PATCH 6 and 7 are just the simplefb patches for A64.

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 DE2 CCU related device tree nodes
  arm64: allwinner: a64: add simplefb for A64 SoC
  arm64: allwinner: a64: add HDMI regulator to all DTs' simplefb_hdmi
