Merge tag 'clkdev-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic into clk-legacy

Pull "clean up legacy clock interfaces" series from Arnd Bergmann:

A recent discussion about legacy clk interface users revealed
that there are only two platforms remaining that provide their own
clk_get()/clk_put() implementations, MIPS ar7 and and m68k coldfire.

I managed to rework both of these to just use the normal clkdev code,
and fold CONFIG_CLKDEV_LOOKUP into CONFIG_HAVE_CLK as it is now shared
among all users.

As I noticed that the ar7 clock implementation and the ralink version
are rather trivial, I ended up converting those to use the common-clk
interfaces as well, though this is unrelated to the other changes.

* tag 'clkdev-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
  clkdev: remove unused clkdev_alloc() interfaces
  clkdev: remove CONFIG_CLKDEV_LOOKUP
  m68k: coldfire: remove private clk_get/clk_put
  m68k: coldfire: use clkdev_lookup on most coldfire
  mips: ralink: convert to CONFIG_COMMON_CLK
  mips: ar7: convert to CONFIG_COMMON_CLK
  mips: ar7: convert to clkdev_lookup
