My SPI Slave driver works, but without DMA..
it seems DMA is disable in slave mode, how can you enable it?

I have a SPI driver for slave mode that works, but have found that it will clock 1 byte out when the SPI clock runs even if CS is inactive. So ideally, the SPI clock should be gated with CS on the slave device if there are other slave devices on the bus.

I’m afraid not. Maybe googling around will help.

Ah, bummer!
In that case can you recommend any resources to achieve the same?

Yes, but it’s commissioned work, so I can’t disclose it.

Do you have a full working example of the implemented SPI slave driver?

Did you try with more than one slave on the bus? From what I’ve seen on an i.MX6ULL the MISO line doesn’t go tristate properly on deasserting SS.
