• f4b89764c   dmaengine/ste_dma40: use AMBA PrimeCell helper macros ... Browse Code »

  The DMA40 is not a PrimeCell from ARM, but it still use the same
  ID registers. So let's utilize the existing macros in the
  PrimeCell header to identify manufacturer and revision of the IP
  block instead of reinventing the wheel.

• d49278e33   dmaengine: dma40: Add support to split up large elements ... Browse Code »

  The maximum transfer size of the stedma40 is (64k-1) x data-width.
  If the transfer size of one element exceeds this limit
  the job is split up and sent as linked transfer.

• 698e4732e   DMAENGINE: ste_dma40: rewrote LCLA entries allocation code ... Browse Code »

  LLI allocation is now done on job level instead of channel level.
  Previously the maximum length of a linked job in hw on a logical
  channel was 8, since the LLIs where evenly divided. Now only
  executing jobs have allocated LLIs which increase the length to
  a maximum of 64 links in HW.
