Subject: [PATCH V3 00/11] add clock driver for Spreadtrum platforms

This series adds Spreadtrum clock support together with its binding
documentation and devicetree data.

Any comments would be greatly appreciated.

Thanks,
Chunyan

Changes from V2: (http://lkml.iu.edu/hypermail/linux/kernel/1707.1/01504.html)
* Switch to use regmap to access registers;
* Splited all clocks into 16 separated nodes, for each belongs to a single address area; 
* Rearranged the order of clock declaration in sc9860-clk.c, sorted them upon the address area;
* Added syscon device tree nodes which will be quoted by the node of clocks which are in
  the same address area with the syscon device;
* Revised the binding documentation according to the dt modification. 

Changes from V1: (https://lkml.org/lkml/2017/6/17/356)
* Address Stephen's comments:
  - Switch to use platform device driver instead of the DT probing mechanism.
  - Move the common clock macro out from vendor directory, but need to remove those
    overlap code from other vendors (such as sunxi-ng) once this get merged.
  - Add support to be built as a module.
  - Add 'sprd_' prefix for all spin locks used in these drivers.
  - Mark input parameter of sprd_x with const.
  - Remove unreasonable dependencies to CONFIG_64BIT.
  - Add readl() after writing the same register.
  - Remove CLK_IS_BASIC which is no longer used.
  - Remove unnecessery CLK_IGNORE_UNUSED when defining a clock.
  - Change to expose all clock index.
  - Use clk_ instead of ccu.
  - Add Kconfig for sprd clocks.
  - Move the fixed clocks out from the soc node.
  - Switch to use 64-bit math in pll driver instead of 32-bit math.
* Revise binding documentation according to dt modification.
* Rename sc9860.c to sc9860-clk.c
