DMA MemoryToMemory using Timer for delivery rate?

Given an F4 (F405 and F429) or even F2 ..

Is it possible for a DMA to be both MemoryToMemory and have the rate of delivery be set by a timer?

ie: I'm effecting a copy from an array in RAM, to a GPIO. (a byte at a time, say, otherwise I could use SPI tricks.)

With MemoryToPeripheral I think you can do it, but is M2M full speed only?

Or is it possible to refer to a GPIO as a peripheral somehow?

Thank you my friends,

jeff
