The docs seem to be outdated somewhat. As an example there is a list of sysfs entries described at the bottom of the page. A lot of these either do not exist or have changed names, and a lot of new ones seem to be added that are not listed in the docs. Is this site the wrong place to be looking or are the docs simply out of date? (If the docs are out of date then maybe we can help you maintain them.) Regards, James
