Hi Patrick, welcome to RIOT! I'm not the best specialist of the topic, maybe others will have complementary advice (or may correct me). Can you scan through the wikipage on this topic [1] ?
For the L4, pm is not there yet. What you could do is look at [2] an consider extending for L4. Then if you mimic what is done for the L0 [3] by activating the pm_layered module, you will have access to the api: if you activate pm_layered, you have access to pm_set for manual setting (or you can let pm_layered autopilot the pm). There are some use cases with GPIO or UART which require special care / manual settings. And: contributions are welcome!
