Hi Erwin,
I think you are referring to the "dummy" byte at the beginning of every
spi command which ensures the 8 clock cycles between all commands. I am
not sure about the deactivated chip select, this is getting sent with an
active chip select as part of the spi_message.
union mmc_spi_command {
u8 buf[7];
struct {
u8 dummy; <-- Here
u8 code;
u8 addr1;
u8 addr2;
u8 addr3;
u8 addr4;
u8 crc;
} command;
};

Hello Steve,
does your driver take care about sending 8 clock cycles with deasserted
CS at the end of a transaction so that DO is tristated? I think that the
2.6 spi subsystem doesn't support sending clocks with deactivated
chipselect.
Regards,
Erwin

Hi Greg,
Likewise, a cleaned up version of the spi mmc patch.
BTW You can ditch the MCF IPS driver patch I sent. I'll send a new
version
based on mmap at some point.
Cheers,
Steve
