[PATCH 0/8] clk: sunxi-ng: Lifetime fixes and module support

[Samuel Holland]

This series makes the CCU drivers a bit better behaved, by allowing them
to be cleanly loaded/unloaded and bound/unbound without leaking memory
or crashing.

- Patches 1 fixes some object lifetime and reference counting issues
  with the drivers.
- Patch 2 disarms a sysfs footgun.
- Patch 3 takes advantage of the structure added in patch 1 to improve
  performance a bit by splitting up the lock.
- Patches 4-8 allow the drivers and CCU core to be built as modules.
  As part of this, patch 7 converts most of the early OF providers to
  platform drivers.

Samuel Holland (8):
  clk: sunxi-ng: Unregister clocks/resets when unbinding
  clk: sunxi-ng: Prevent unbinding CCUs via sysfs
  clk: sunxi-ng: Use a separate lock for each CCU instance
  clk: sunxi-ng: Rename files to match Kconfig and drivers
  clk: sunxi-ng: Export symbols used by CCU drivers
  clk: sunxi-ng: Allow drivers to be built as modules
  clk: sunxi-ng: Convert early providers to platform drivers
  clk: sunxi-ng: Allow the CCU core to be built as a module
