* gpu: nvgpu: avoid redundant enable/disable PGDaniel Fu2018-07-18
| | | | | | | | | | | | | | | | | | ELPG powergate is refcounted. We should not enable/disable it, if it's already so. Or it will break the PG disable/enable function.

* gpu: nvgpu: add pm_rumtime fixesNitin Kumbhar2018-07-12
| | | | | | | | | | | | | | | | | | | | | | | Runtime PM is enabled only for iGPU and not for dGPU. For dGPU, the .probe() of driver pm_runtime_disable()s, if rail-gating is not enabled. With nvgpu kernel module load/unload, .probe() is called multiple times for same struct device *. This results in an overflow of disable_depth (3 bit refcount) and enables runtime PM on 8th iteration and calls RTPM routines even if it's disabled. To effectively manage pm_runtime_disable(), move it from common nvgpu_remove() to iGPU/dGPU specific routines. Also, add restore pm_runtime state of device on driver .remove().
