406c4cc4a8 reset: sunxi: Reuse the platform data from the clock driver
The clock and reset drivers use the exact same platform data. Simplify
them by sharing the object. This is safe because the parent device
(the clock device) always gets its driver model callbacks run first.

88a48da82d clk: sunxi: Convert driver private data to platform data
All of the driver private data should really be platform data since it
is determined statically (selected by the compatible string or extracted
from the devicetree). Move everything to platform data, so it can be
provided when binding the driver. This is useful for SPL, or for
instantiating the driver as part of an MFD.

cd57709fe5 clk: sunxi: Use a single driver for all variants
Now that all of the variants use the same bind/probe functions and ops,
there is no need to have a separate driver for each variant. Since most
SoCs contain two variants (the main CCU and PRCM CCU), this saves a bit
of firmware size and RAM.

898aaff3a5 reset: sunxi: Get the reset count from the CCU descriptor
This allows all of the clock drivers to use a common bind function.

41555ab6fe clk: sunxi: Store the array sizes in the CCU descriptor
The reset array size is currently used for bounds checking in the reset
driver. The same bounds check should really be done in the clock driver.

Currently, the array size is provided to the reset driver separately
from the CCU descriptor, which is a bit strange. Let's do this the usual
way, with the array sizes next to the arrays themselves.

185f812c41 doc: replace @return by Return:
Sphinx expects Return: and not @return to indicate a return value.

21d314a661 clk: sunxi: Move header out of arch directory
The CCU header is only used by the DM drivers, not any platform code.
Its current location adds an artificial dependency on CONFIG_ARM and
ARCH_SUNXI, which will be problematic when adding the CCU driver for
a RISC-V sunxi platform.
