Dr. Lu,
In mcp55_smbus.h
static int do_smbus_send_byte(unsigned smbus_io_base, unsigned device,
unsigned char val)
{
.....
outb(0, smbus_io_base + SMBHSTCMD);
.....
}
I wonder why you write 0 to SMBHSTCMD ? if we are using a smbus_hub , I
think we should write the channel number we want to enable to this
register. for example , if my memory controller is on channel 2 , we should
write outb(2,smbus_io_base+SMBHSTCMD).
So could that be changed to outb(val,smbus_io_base + SMBHSTCMD) ?
Thanks
bxshi
