Unfortunately, the next/dt branch of arm-soc is not necessarily stable so should *not* be merged. In fact none of the arm-soc branches should be considered stable. As was already mentioned, this should be split up into driver changes and DTS changes through arm-soc. They'll both merge for v3.12. BTW, how did this patch get merged without a signoff/ack from the OMAP DT maintainer in the first place? Hmm, looks like Benoit was not copied nor was linux-omap or linux-arm-kernel copied in the original mails. Kevin
