[PATCH 0/8] clocksource: sunxi: Timer fixes and cleanup

Hi everyone,

The first timer code we merged when adding support for the A13 some time back
was mostly a clean up from the source drop we had, without any documentation.
This happened to work, but the code merged in turned out to be far from
perfect, and had several flaws.

This patchset hopefully fixes these flaws, and cleanup most of the driver as
well, to end up in an almost complete rewrite of it (even though it's not that
long).

It also finally adds a clocksource from the free running counter found in the
A10/A13 SoCs.

These flaws have all been spotted when trying to add the A31 support, work that
is still ongoing, but will hopefully benefit from this patchset as well.

Thanks,
Maxime
