* Name: stm32_pminitialize
|
|
*
|
|
* Description:
|
|
* This function is called by MCU-specific logic at power-on reset in
|
|
* order to provide one-time initialization the power management subsystem.
|
|
* This function must be called *very* early in the initialization sequence
|
|
* *before* any other device drivers are initialized (since they may
|
|
* attempt to register with the power management subsystem).
|
|
*
|
|
* Input Parameters:
|
|
* None.
|
|
*
|
|
* Returned Value:
|
|
* None.
