Subject: [PATCH v2 0/7] Allwinner A64 DE2 CCU support with dedicated DE2 bus driver

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
