Joel Stanley 785b62167d clk: gemini: Read status before using the value
The probe does a shift and mask of val without having read it from the hardware.

Linus Walleij 846423f967 clk: Add Gemini SoC clock controller
The Cortina Systems Gemini (SL3516/CS3516) has an on-chip clock
controller that derive all clocks from a single crystal, using some
documented and some undocumented PLLs, half dividers, counters and
gates. This is a best attempt to construct a clock driver for the
clocks so at least we can gate off unused hardware and driver the
PCI bus clock.
