GPU Power Management Infrastructure
Registered by
Chunsang Jeong
For GPU power saving, common power management infrastructure is needed, which provide effective power saving methods for GPUs, outside (possibly inside) of GPU driver by getting GPU status, especially for those which don't have internal PMU(Power Management Unit).

cpuidle.c / cpufreq.c
- Common structure to get "utilization" from GPU driver.
- GPU clock and power gating with regulator to GPU power domain from system.
- Interface for closely coupled to CPU power levels.
