+ The driver provides support for AMD Power Management Controller
+ primarily responsible for S2Idle transactions that are driven from
+ a platform firmware running on SMU. This driver also provides a debug
+ mechanism to investigate the S2Idle transactions and failures.
+
+ Say Y or M here if you have a notebook powered by AMD RYZEN CPU/APU.

+ If you choose to compile this driver as a module the module will be

+ help
+ AMD MP2 STB function provides a data buffer used to log debug
+ information about the system execution during S2Idle suspend/resume.
+ A data buffer known as the STB (Smart Trace Buffer) is a circular
+ buffer which is a low-level log for the SoC which is used to debug
+ any hangs/stalls during S2Idle suspend/resume.
+
+ Creates debugfs to get STB, a userspace daemon can access STB log of
+ last S2Idle suspend/resume which can help to debug if hangs/stalls
+ during S2Idle suspend/resume.
