Good idea. Another need may be a sdio_read[bwl]_sync, which will poll for the end of the cmd52s, instead of waiting for the irq. This polling is faster than wait_for_completion/irq/tasklet/complete mechanism, which involve several context switches. > Endianness can also be handled there (SDIO are always LE). I dont remember sdio spec forcing HW registers to be LE. Function 0 registers are (BLKSZ for ex), but Function 1-7 register may be BE if the designers found an advantage to it.. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
