    Subject[PATCH 3/9] dmaengine: dw-edma: Add HDMA remote interrupt configuration
    Date
    From: Kory Maincent <kory.maincent@bootlin.com>

    Only the local interruption was configured, remote interrupt was left
    behind. This patch fix it by setting stop and abort remote interrupts when
    the DW_EDMA_CHIP_LOCAL flag is not set.

    Signed-off-by: Kory Maincent <kory.maincent@bootlin.com>
    Fixes: e74c39573d35 ("dmaengine: dw-edma: Add support for native HDMA")
    ---

    This patch is fixing a commit which is only in dmaengine tree and not
    merged mainline.
