With support for amba-pl08x driver, on S3C64xx the generic DMA engine API can be used instead of the private s3c-dma interface.
I'm still getting issues for SPI with this:
[ 50.952845] s3c64xx-spi s3c6410-spi.0: Failed to get RX DMA channel [ 50.953520] spi_master spi0: failed to prepare transfer hardware
when I test (with -next with this series applied on top), this is from the first transfer that tries to DMA - there's actually no RX data. No errors are reported by the DMA controller itself. I'm also getting crashes setting up the audio DMA while derferencecing the channel.
This is without DT - are there any hookups missing because of that?
Hmm, strange.
I've been testing this without any significant patches, like PWM, CCF or DT support, just everything from the branch I pointed to and some board- specific patches to help in debugging.
Anyway, this is the exact branch I've been using:
git://github.com/tom3q/linux.git v3.12-pl080-devel
