Hi Robert Baldyga, In order to test this patch, the current mainline kernel requires additional patches to support device-tree. The following patches are necessary. http://lists.infradead.org/pipermail/linux-arm-kernel/2013-June/179920.html http://lists.infradead.org/pipermail/linux-arm-kernel/2013-June/179921.html http://lists.infradead.org/pipermail/linux-arm-kernel/2013-June/179922.html The last one should be modified for your machine.
