You might want to Cc linux-arch@vger.kernel.org on future iterations of this patchset where there's less "noise" than on LKML and the relevant people are more likely to notice ;) Likewise, the device-tree specific bits (e.g. the bindings documentation) should probably be Cc'ed to devicetree@vger.kernel.org Tobias
