• 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.
