Previously, -the dmac driver assumed that an sg request should transfer all -the data in the scatterlist, which would break in this case. - -Resolve this by passing the number of blocks to transfer explicitly. -This will probably fix a number of cases where the mmc controller -seemed to be out of sync with the dma controller. - -Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> ---- - drivers/mmc/atmel-mci.c | 3 +-- - 1 file changed, 1 insertion(+), 2 deletions(-) - -Index: linux-2.6.18-avr32/drivers/mmc/atmel-mci.c -=================================================================== ---- linux-2.6.18-avr32.orig/drivers/mmc/atmel-mci.c 2007-01-15 15:39:13.000000000 +0100 -+++ linux-2.6.18-avr32/drivers/mmc/atmel-mci.c 2007-01-15 15:39:25.000000000 +0100 -@@ -51,7 +51,6 @@ struct atmel_mci_dma { - struct dma_request_sg req; - unsigned short rx_periph_id; - unsigned short tx_periph_id; -- int blocks_left; - }; - - struct atmel_mci { -@@ -428,6 +427,7 @@ static u32 atmci_prepare_data(struct mmc - mci_writel(host, BLKR, (MCI_BF(BCNT, data->blocks) - | MCI_BF(BLKLEN, data->blksz))); - host->dma.req.block_size = data->blksz; -+ host->dma.req.nr_blocks = data->blocks; - - cmd_flags = MCI_BF(TRCMD, MCI_TRCMD_START_TRANS); - if (data->flags & MMC_DATA_STREAM) -@@ -454,7 +454,6 @@ static u32 atmci_prepare_data(struct mmc - host->dma.req.data_reg = host->mapbase + MCI_TDR; - } - host->dma.req.sg = data->sg; -- host->dma.blocks_left = data->blocks; - - dma_prepare_request_sg(host->dma.req.req.dmac, &host->dma.req); - |
