Hi Jon, That is a nice follow up to the OMAP idle code clean up, cf. http://lists.linaro.org/pipermail/linaro-dev/2010-October/001084.html. It would be nice to see how the code is organized and the impact of integrating it into the kernel. Regards, Jean On Tue, Oct 12, 2010 at 12:39 PM, Jon

Well, my plan was to... er... post a message on linaro-dev and see happened! And yes, refactor as an ARM-common driver + SoC-specific stubs, that sounds about right. I plan to work on the Linux integration from 1st December. I have done some Linux kernel work before but I'm a little rusty.
