For the sake of bitsec, at least patches #7 and #8 need to be one patch. That said, if I apply the series and then check out the commit at patch #7, you need to all mxs-dma client drivers, mxs-mmc, gpmi do not break. > In the new GPMI version, some hardware behavior changes. > The WAIT4END bit should be set in the middle one of the ECC READ page DMA chain. > The DMA chain should be set like this: > > +-----+ +-----+ +-----+ > | cmd | ------------> | cmd | ------------------> | cmd | > +-----+ +-----+ +-----+ > ^ ^ > | | > | | > set WAIT4END here too set WAIT4END here > > Please read the comment in patch "MXS-DMA : add more flags for MXS-DMA". > > Huang Shijie (10): > MXS-DMA : move the mxs-dma.h to a more common place > MXS-DMA : change the header > MXS-MMC : change the DMA header file > MTD/GPMI : change the DMA header file > ASoc : change the DMA header file > MXS-DMA : add more flags for MXS-DMA > MXS-DMA : change the last parameter of mxs_dma_prep_slave_sg() > MXS-MMC : use the new DMA flags > MTD/GPMI : add a new field `gpmi_version` > MTD/GPMI : change the code for new DMA interface > Please try to make these subject prefix consistent with the existing ones in the tree. You can get them from 'git log' output. For example "mxs-dma: ..." is better than "MXS-DMA : ...". -- Regards, Shawn -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
