This set is a v2 of my original patchset "zynq COMMON_CLK support" [1].

This patchset is on top of the arm-next in the Xilinx tree[2], and also
dependent on my patch "serial: xilinx_uartps: kill CONFIG_OF
conditional", which I've removed from this patchset at Michal Simek's request.

For easy testing, I've made available a branch with my changes here[3].

Changes since v1:
  - Dropped the moving of the TTC driver.  This will be done in a later
    patchset.
  - Fixed TTC periodic tick frequency calculation
  - Updated basic peripheral clk to support devices with less than two
    derivative clks.
  - Fixed dts issues in the uart and ttc (thanks to Lars-Peter Clausen and Michal Simek).
  - Split out the creation of the clk drivers and the enabling of the
    drivers for the platform into separate patches.
  - Updated clk initialization functions to 'bail out' when an error
    condition is hit.
  - Addressed stylistic feedback from Lars-Peter Clausen.

Patch 1 performs a dts file split for zynq, creating a generic zynq-7000.dtsi
snippet and a zynq-zc702.dts board specific description.

Patch 2 introduces the zynq clock drivers and bindings.

Patch 3 enables the zynq clock drivers when building for zynq, and
adds updates the zynq device trees to use the bindings.

Patch 4 updates the xilinx uartps driver to acquire rate information via
the clk bindings.

Patch 5 updates the xilinx ttc driver to acquire rate information via
the clk bindings.
