Subject: [PATCH V1 0/9] add clock driver for Spreadtrum platforms

In the last cycle, the patches support Whale2 sc9860 mobile chip have been
merged. This patchset adds clock driver which is used on almost all
Spreadtrum SoCs.

This is a rewrite of Spreadtrum's original clock driver[1] according to the
comments[2] from Stephen Boyd.

This series also adds Spreadtrum clock binding documentation and devicetree
data.

Any comments would be greatly appreciated.

Thanks,
Chunyan
