## Summary This PR intends to improve the HR Timer by defining critical sections via spinlock APIs, which are more efficient than the standard critical section APIs in regards to protecting the HR Timer resources (e.g. timer list) and hardware registers (SYSTIMER) against concurrent accesses. Besides, the use of a device-local spinlock improves the driver SMP-awareness and paves the way to supporting newer multicore chips (e.g. ESP32-P4). ## Impact Only to the HR Timer, which is not yet used by any other Kernel component. ## Testing Validating via internal CI testing. -- This is an automated message from the Apache Git Service.
