    Subject[PATCH 0/2] dmaengine: hdmac: Implement interleaved transfers support
    Date
    Hi everyone,

    This patchset implements the interleaved transfer capability found on
    some AT91 SoCs.

    The hardware actually support a somewhat similar mode called
    picture-in-picture, that allows to transfer a squared portion of a
    framebuffer.

    That actually means that the interleaved transfer that this hardware
    support will need to have the same size and ICGs across all its
    chunks.

    It has been tested on the SAMA5D36.

    Let me know what you think!
    Maxime
