Dear All,

This patchset is an attempt to submit the last piece of missing code
to have proper support for Exynos5433 SoCs based TM2(e) boards. It
performs a cleanup of timer configuration, which so far needed various
out-of-tree workarounds. The fixes provided by this patchset are also
needed for add proper support for system suspend/resume.

Best regards
