* gpu: nvgpu: MISRA Rule 21.2 header guard fixessmadhavan2018-09-25
| | | | | | | | | | | | | | | | | | | | | | MISRA rule 21.2 doesn't allow the use of macro names which start with an underscore. These leading underscores are to be removed from the macro names. This patch will fix such violations in nvgpu by renaming them to follow the convention,'NVGPU_PARENT-DIR_HEADER-NAME' when there is no keyword repetition between file name and directory or 'NVGPU_HEADER-NAME' when there is repetition.

| | | | | | | | | | | | | | | | Fix MISRA 10.3 violations in mclk_gp106.c. Cleanup cases where values were being assigned to narrower types. Changes in mclk_gp106.c required updates to other files to resolve errors and prevent introducing new violations.

| | | | | | | | | | | | | | | | | | | | 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.
