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
