Re: [PATCH v2 1/3] mtd: rawnand: cadence: support deferred prob when DMA is not ready

Hello,

My apologies for the confusion. Slave DMA terminology used in cadence nand controller bindings and driver is indeed confusing.

To answer your question it is, 1 - External DMA (Generic DMA controller).

Nand controller IP do not have embedded DMA controller (2 - peripheral DMA).

FYR, how external DMA is used. https://elixir.bootlin.com/linux/v6.13.1/source/drivers/mtd/nand/raw/cadence...

In this case we should have a dmas property (and perhaps dma-names), no?
