From: Muralidharan Karicheri <m-karicheri2@xxxxxx>
Rebased to latest linux-next tree
Updated based on Kevin's comments on clock configuration.
The ccdc now uses a generic name for clocks. master and slave. On individual platforms
these clocks will inherit from the platform specific clock. This will allow re-use of
the driver for the same IP across different SoCs.
Following are the changes done:-
1) clocks are configured using generic clock names
2) converting the driver to a platform driver
3) cleanup - consolidate all static variables inside a structure, ccdc_cfg
