Johnny Liu	3db3e1ee88	devfreq: Disable watermark when switching governor ... Before switching to another governor, tegra_wmark governor should disable watermarks so that watermark interrupts won't get triggered and occupy the CPU resource.

Johnny Liu	0da771f275	devfreq: Support suspend and resume in tegra_wmark ... When devfreq_suspend_device get called, tegra_wmark will disable the upper and lower watermark thresholds so that no DFS logic get triggered after the suspension. When devfreq_resume_device get called, tegra_wmark will enable back the upper and lower watermark thresholds so that interrupt-driven DFS logic can work properly.

Johnny Liu	d06443deae	devfreq: Add tegra_wmark governor ... The tegra_wmark governor can be used e.g. with DRM clients, such as VIC, NVDEC, NVENC, and NVJPG. This governor tightly collaborates with the actmon hardware used for monitoring the active time of the underlying DRM clients.
