Måns, There are few known gaps in linux-ti-staging 3.8 kernel compared to the old PSP 3.2 kernel, as it relates to am335x. Moreover, ti2013.04.00 release was specific to omap5. If you need am335x feature completeness now, you can always use 3.2 kernel by setting PREFERRED_PROVIDER and PREFERRED_VERSION in your config. Going forward, the gaps will be closed in mainline. -- Denys
