I think I was not clear enough. I meant sound/soc/fsl/mpc5200_dma.c, not the actual Bestcom DMA driver.
Ah, okay, sorry misunderstood that.
Btw, I am writing a DMA-less driver for the MPC5121e for now. It uses the PSC FIFO and FIFO alarm interrupts. DMA support could be added later, when de MPC5121 DMA driver becomes capable of doing device IO.
OK, seems sensible for a start. MPC5121 does not get much love, so small steps are definately a good idea.
1.- I can't test it on a MPC5200B, so therefor I need help.
I can do tests.
If you could try out latest mainline, to see if the driver still works, that would be great for a start. I am almost certain it either doesn't work anymore, or you have a 50% chance it crashes while booting.
OK, I will leave for Prague in the next hours, so until I return, I can do only remote testing. But I should see OOPSes this way nonetheless. Might take a few days, though...
