2021-08-16	drm/amd/pm: drop the unnecessary intermediate percent-based transition	Evan Quan	1	-10/+6
	Currently, the readout of fan speed pwm is transited into percent-based and then pwm-based. However, the transition into percent-based is totally unnecessary and make the final output less accurate.

2021-08-16	drm/amd/pm: correct the fan speed PWM retrieving	Evan Quan	1	-9/+15
	The relationship "PWM = RPM / smu->fan_max_rpm" between fan speed PWM and RPM is not true for SMU11 ASICs. So, we need a new way to retrieving the fan speed PWM.

2020-08-14	drm/amd/pm: optimize the power related source code layout	Evan Quan	1	-0/+357
	The target is to provide a clear entry point(for power routines). Also this can help to maintain a clear view about the frameworks used on different ASICs. Hopefully all these can make power part more friendly to play with.
