pm: Allow override constraints implementation (8beb3423) · Commits · Wenxi XU / zephyr

Implement constraint API as weak symbols so applications or platform can override them. Constraints are a high-level abstraction to inhibit the power subsystem of using certain power states. Some platforms can have their own way to set/release constraints in their drivers that are not part of Zephyr's code base. Signed-off-by:
