I also ported over most PXA peripheral drivers, but that will take some more time to settle. I'll post those in a separate series. Up front, here are some patches for the mmp-pdma that can be reviewed and merged independently. With these patches applied, I can successfully use pxa3xx-nand, pxamci and audio on a custom pxa3xx board. I'm including two patches from Xiang Wang which have been posted but not yet merged, as far as I can tell. Many thanks, Daniel Daniel Mack (10): dma: mmp_pdma: factor out DRCMR register calculation dma: mmp_pdma: fix maximum transfer length dma: mmp_pdma: add filter function dma: mmp_pdma: make the controller a DMA provider dma: mmp_pdma: print the number of channels at probe time dma: mmp_pdma: remove duplicate assignment dma: mmp_pdma: add support for byte-aligned transfers dma: mmp_pdma: implement DMA_PAUSE and DMA_RESUME dma: mmp_pdma: add support for residue reporting dma: mmp_pdma: add support for cyclic DMA descriptors Xiang Wang (2): dma: mmp_pdma: add protect when alloc/free phy channels dma: mmp_pdma: clear DRCMR when free a phy channel drivers/dma/mmp_pdma.c | 274 +++++++++++++++++++++++++++++++++++++++---- include/linux/dma/mmp-pdma.h | 15 +++ 2 files changed, 263 insertions(+), 26 deletions(-) create mode 100644 include/linux/dma/mmp-pdma.h -- 1.8.3.1
