* gpu: nvgpu: Fold T19x code back to main code pathsTerje Bergstrom2018-01-23
| | | | | | | | | | | | | Lots of code paths were split to T19x specific code paths and structs due to split repository. Now that repositories are merged, fold all of them back to main code paths and structs and remove the T19x specific Kconfig flag.

* gpu: nvgpu: gv11b: enable devfreqseshendra Gadagottu2018-01-19
| | | | | | | | | | | | | | | | | | | | | | Enable devfreq for gv11b by enabling ""nvhost_podgov" governor in platform data. Reuse scaling functions from gp10b/gk20a. Remove emc floor on railgate for power saving and make max emc frequency as floor in rail-ungate for faster gpu boot.

| | | | | | | | | | | | | | | | | | Remove nvgpu internal flag indicating that TSGs are required. We now require TSGs always. This also fixes a regression where CE channels were back to using bare channels on gp106.
