Great, thanks!

I see the update in the master branch, so I'm resending the CNS3xxx
patchset, v4 this time (full change log is at the very bottom).

These patches also available in the CNS3xxx GIT tree, on top of your
current 'master' branch. Please pull if the patches look OK to you.

(Note, if you try to pull it into your 'devel' branch, you'll see a
trivial conflict in arch/arm/Kconfig, but it isn't caused by any of
my commits in there, the same conflict will pop up if you merge
your master branch into devel.)

The formal pull request:

Changes since v3:

- Removed static inline __io function from mach/io.h, this was a
  leftover. Noticed by Russell King.

Changes since v2:

- We noticed that timer2 (which was used as a clock source) causes
  nanosleep system call to misbehave. Until debugged, the timer2
  support is removed.

  It's fine since timer1 is still used as a clockevent, and provides
  all needed timekeeping functionality. With these patches we want
  a minimal (but rock solid) CNS3xxx support, all non-essential
  features can wait.

  I.e. support for the second timer can be added as a separate
  patch.

- Updated some PCIe register definitions to make PCIe integration
  more smooth.

- Updated defconfig.

Changes since v1:

- Addressed Russell's comments;
- CNS3420VB board support split into its own patch per Sergei's
  comment;
- This series no longer include AHCI and SDHCI patches. Because of
  dependencies on other trees they aren't yet suitable for inclusion,
  so no need to repost them again.

Thanks,
