Hook up the external start function pointer for the 83xx controller. Signed-off-by: Ira W. Snyder --- Though there is no way to enable external start in the mainline driver, the DMA_SLAVE patch I posted last week does give the ability to enable external start. I have tested this patch along with the DMA_SLAVE patch using a driver for some custom hardware that uses the external DMA control lines. drivers/dma/fsldma.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/dma/fsldma.c b/drivers/dma/fsldma.c index db07113..b2fd35e 100644 --- a/drivers/dma/fsldma.c +++ b/drivers/dma/fsldma.c @@ -1099,9 +1099,9 @@ static int __devinit fsl_dma_chan_probe(struct fsl_dma_device *fdev, switch (new_fsl_chan->feature & FSL_DMA_IP_MASK) { case FSL_DMA_IP_85XX: - new_fsl_chan->toggle_ext_start = fsl_chan_toggle_ext_start; new_fsl_chan->toggle_ext_pause = fsl_chan_toggle_ext_pause; case FSL_DMA_IP_83XX: + new_fsl_chan->toggle_ext_start = fsl_chan_toggle_ext_start; new_fsl_chan->set_src_loop_size = fsl_chan_set_src_loop_size; new_fsl_chan->set_dest_loop_size = fsl_chan_set_dest_loop_size; } -- 1.5.4.3
