That's a bit odd. How is your driver getting the IRQ its requesting?
Are you using the same .dts in both cases?

So after I've built the kernel to include the dmaengine and fsldma
drivers, my driver is allowed
to register its ISR via request_irq. However, if these drivers are
not installed then request_irq
fails in my driver. So it seems that there is some other
initialization happening before
request_irq is being called in fsldma and subsequently my driver.
Does anyone know what this is?

The dmaengine provides a generic set of APIs w/a FSL dma backend. It
might be the case that your need of dma doesnt fit into the current
set of APIs.

Well in that case wouldn't I need to use the fsldma driver? Or is
dmaengine a generic dma driver?

I'm trying to write a driver that would make use of the DMA on the

there something that I need to
do before I call request_irq, maybe in the dts or somewhere else?
any reason you aren't using the dmaengine driver?
