platform_bus: allow custom extensions to system PM methods (190e8370) · Commits · 戴 / test

When runtime PM for platform_bus was added, it allowed for platforms to customize the runtime PM methods since they are defined as weak symbols. This patch allows platforms to also extend the system PM methods with custom hooks so runtime PM and system PM extensions can be managed together by custom platform-specific code. Signed-off-by:
