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

[Chunyan Zhang <chunyan.zhang@spreadtrum.com>]

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
