* gpu: nvgpu: clk arbiter skeletonThomas Fleury2016-12-27
| | | | | | | | | | | | | | | | | | | | Add clock arbiter skeleton with support of clock sessions, notifications on clock changes, request numbering, and asynchronous handling of clock requests. Provides minimum behaviour to allow unit tests implementation. Actual arbitration and clock settings will be done separately. For now, dummy arbiter keeps last requested target mhz. Actual arbiter may move to a lockless implementation.

* gpu: nvgpu: support to parse VF tableVijayakumar2016-12-27
| | | | | | | | | | | | | | | | | | | | | | | | JIRA DNVGPU-123 function was added to retrieve V for F or F for V for a given clock domain. Clock domain can be master or slave. F or V can be intermediate point between two successive V or F values in VF table. VF table should be cached before calling this function. A F value below Fmin will return Vmin. F > Fmax will return error A V value above Vmax wil return F max. A V value below Vmin will return error.
