3 The FDMA is a general-purpose direct memory access controller capable of
4 supporting 16 independent DMA channels. It accepts up to 32 DMA requests.

14 - reg		: Should contain an entry for each name in reg-names
15 - reg-names	: Must contain "slimcore", "dmem", "peripherals", "imem" entries
16 - interrupts	: Should contain one interrupt shared by all channels
17 - dma-channels	: Number of channels supported by the controller

19 - clocks	: Must contain an entry for each clock
