Re: [alsa-devel] [PATCH] dma: add new DMA control commands

So we can't stream data from the chip? About time to adjust the MTD framework to allow that. Maybe implement a command queue?

IMHO, it's not possible. Because the READ-PAGE(00h-30h) command needs to check the busy status which means we have to stop in the middle, so we can not chain the all the read-pages DMA commands.
