CS2000 needs AUDIO_CLKOUT as master clock which is generated
by Renesas sound, and Renesas sound needs CS2000 as ADUIO_CLK_B.
Because of this relationship, it will be dead-lock when driver probe.

cs2000: clk_multiplier@4f {
        ...
        clocks = <&rcar_sound 0>, <&x12_clk>;
        ...
};

&rcar_sound {
        ...
        assigned-clocks = <&cs2000>;
        ...
};

This patch is using dummy audio_clkout to avoid this issue.

  A reverse select is often more user-friendly, but in this case, it

 "Found a couple of brown paper bag bugs with the prev pull request
  (including a SMP build breakage report from Guenter).  Since these are
  urgent I also decided to send over a bunch of other pending fixes
  which could have otherwise waited an rc or two.

  Summary:

   - A bunch of brown paper bag bugs (MAINTAINERS list email, SMP build
     failure)
   - cpu_relax() now compiler barrier for UP as well
   - handling of userspace Bus Errors for ARCompact builds"

* tag 'arc-4.4-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc:
  ARC: Fix silly typo in MAINTAINERS file
  ARC: cpu_relax() to be compiler barrier even for UP
  ARC: use ASL assembler mnemonic
  ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
  ARC: remove extraneous header include
  ARCv2: lib: memcpy: use local symbols

cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per
recent discussions, it is safer to make it a compiler barrier
unconditionally.
