The Embedded Linux Conference (ELC) is the premier vendor-neutral technical conference for companies and developers using Linux in embedded products. This conference, now in its 9th year, has the largest collection of sessions dedicated exclusively to embedded Linux and embedded Linux developers. ELC is embedded Linux experts talking about solutions to your embedded Linux problems. ELC consists of 3 days of presentations, tutorials and Bird-of-a-Feather sessions. There are over 50 sessions to choose from, on a wide variety of topics.
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.
