Re: [alsa-devel] [PATCH 3/3] dma: edma: Increase maximum SG limit to 20

davinci-pcm uses 16 as the no.of periods. With this, in EDMA we have to allocate atleast 17 slots: 1 slot for channel, and 16 slots the periods.

Due to this, the MAX_NR_SG limitation causes problems, set it to 20 to make cyclic DMA work when davinci-pcm is converted to use DMA Engine. Also add a comment clarifying this.

Applied, thanks
