Merge tag 'sirf-soc-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/baohua/linux into next/cleanup

Merge "ARM: sirf: machine update for 3.16" from Barry Song:

Most of them fix some minor checkpatch issues according to key customers'
requirement. And this patchset also cleanups the clk of clocksource: move
to get clk by dts properity.

* tag 'sirf-soc-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/baohua/linux:
  clocksource:sirf: remove the hardcode for the clk of timers
  irqchip: sirf: fix one minor checkpatch issue
  clocksource: prima2: fix some minor checkpatch issues
  ARM: prima2: rstc: fix some minor checkpatch issues
  + Linux 3.15-rc3
