I believe dma-ranges is supposed to be in the bus (parent) node.
Maybe I'm just going to be perpetually confused by dma-ranges, but how
can I specify that the emac has a different DMA range from another SOC
device, if dma-ranges is in the parent node?
The EMAC itself is capable of 64-bit DMA internally (I should have
included a dma_set_mask call with DMA_BIT_MASK(64) in the driver).
However, the platform typically limits this range. On FSM9900 and
QDF2432, it's 32 bits. On the next server chip, it'll be the full 64
bits. I need some way to handle that.
