Oh, right. We should really be churning the device tree like this - the idea is that the device tree should be stable and independant of kernel versions. It would be better if we were able to go straight to the one without hwmod, especially if Benoit is able to get the underlying changes done soon (which sounded like it might be the case). Could we define and implement the "real" version now (it should be reasonable to code blind except possibly for the DMA channel as it's such a direct mapping) with hwmod left in there as something that's legacy for old kernels?
