  • b7d861d93   DMA: PL330: Merge PL330 driver into drivers/dma/ ... Browse Code »

    Currently there were two part of DMAC PL330 driver for
    support old styled s3c-pl330 which has been merged into
    drivers/dma/pl330.c driver. Actually, there is no reason
    to separate them now.

    Basically this patch merges arch/arm/common/pl330.c into
    drivers/dma/pl330.c driver and removes useless exported
    symbol, externed function and so on.

    The newer pl330 driver tested on SMDKV310 and SMDK4212 boards

  • cd0725152   DMA: PL330: Infer transfer direction from transfer request instead of platform data ... Browse Code »

    The transfer direction for a channel can be inferred from the transfer
    request and the need for specifying transfer direction in platfrom data
    can be eliminated. So the structure definition 'struct dma_pl330_peri'
    is no longer required.

    The channel's private data is set to point to a channel id specified in
    the platform data (instead of an instance of type 'struct dma_pl330_peri').
    The filter function is correspondingly modified to match the channel id.

    With the 'struct dma_pl330_peri' removed from platform data, the dma
    controller transfer capabilities cannot be inferred any more. Hence,
    the dma controller capabilities is specified using platform data.

  • 3e2ec13a8   DMA: PL330: move filter function into driver ... Browse Code »

    The dma channel selection filter function is moved from plat-samsung
    into the pl330 driver. In additon to that, a check is added in the
    filter function to ensure that the channel on which the filter has
    been invoked is pl330 channel instance (and avoid any incorrect
    access of chan->private in a system with multiple types of DMA
    drivers).

  • b3040e406   DMA: PL330: Add dma api driver ... Browse Code »

    Add DMA Engine API driver for the PL330 DMAC.
    This driver is supposed to be reusable by various
    platforms that have one or more PL330 DMACs.
    Atm, DMA_SLAVE and DMA_MEMCPY capabilities have been
    implemented.
