器件型号：TPS65218 主题中讨论的其他器件：AM3358、
工具与软件：
我使用的是 AM3358 CPU 和 TPS65218。
-内核版本5.10.
但是、TPS65218的内核无法正常工作。

* Configure pmic to enter OFF-state instead of SLEEP-state ("RTC-only

*
* For details, see linux-omap mailing list May 2015 thread
* [PATCH] ARM: dts: am335x-bone* enable pmic-shutdown-controller
* In particular, messages:
* www.spinics.net/.../msg118585.html
* www.spinics.net/.../msg118615.html

* You can override this later with
* &tps { /delete-property/ ti,pmic-shutdown-controller; }
* if you want to use RTC-only mode and made sure you are not affected
* by the hardware problems. (Tip: double-check by performing a current
* measurement after shutdown: it should be less than 1 mA.)

由于这种现象、CPU 频率驱动器也无法工作。
我需要调试帮助。
请检查。
