      The 'page' region describes the address space of the page

      used for accessing the DMA channel registers. The 'global'

      region describes the address space of the global DMA registers.

      In the absence of the 'reg-names' property, there must be a

      single entry that covers the address space of the global DMA

      registers and the DMA channel registers.
