Merge branch 'u300-cleanup' of git://git.kernel.org/pub/scm/linux/ker…

…nel/git/linusw/linux-stericsson into next/cleanup

From Linus Walleij <linus.walleij@linaro.org>

This patch set does a number of cleanups and a minor improvement
to U300, paving the way for single zImage and device tree:

- Deprecate ancient platforms to make the following patches easier to
  make...
- Move out one header to platform data and one to the mach-u300 proper
  to depopulate <mach/*>
- Consolidate core machine files
- Convert to sparse IRQs

* 'u300-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  ARM: u300: convert to sparse IRQs
  ARM: u300: move DMA channel header into mach-u300
  ARM: u300: delete remnant clkdev.h file
  ARM: u300: merge u300.c into core.c and rid headers
  pinctrl/coh901: move header to platform data dir
  pinctrl/coh901: retire ancient GPIO block versions
  ARM: u300: retire ancient platforms
