Clock Management in Zephyr RTOS

Explore clock management in Zephyr RTOS through this 40-minute conference talk by Daniel DeGrasse from NXP. Dive into the current clock control APIs in Zephyr, examining their capabilities for querying and setting clock rates, clock gating, and configuring clock roots. Understand the challenges of implementing clock configuration within these APIs, including complex dependency management and large flash footprint requirements. Learn about the device-specific nature of the current clock control API and its limitations in transitioning clocks to lower power states. Discover proposed additions to the clock control API that aim to enable transitions between different clock states, potentially unlocking increased power savings for embedded devices without significant software overhead.
