Common Clock Framework: How To Use It - Gregory Clement, Free Electrons

Sign up or log in to save this to your schedule and see who's attending!

The common clock framework, which was included in the 3.4 kernel in the beginning of 2012, is now mandatory to support all new ARM SoCs. It is also part of the "one zImage to run them all" big plan of the ARM architecture in the Linux kernel. After an introduction on why we needed this framework and on the problems it solves, we will go through the implementation details of this framework. Then, with real examples, we will focus on how to use this framework to add clock support to a new ARM SoC. We will also show how the device tree is used in this process. The last part of the talk will review how device drivers use this framework, using examples taken from various parts of the kernel.This talk is an update of the one given at ELC 2013. It will cover the new features introduced since the beginning of the year.
