Yeah. You're right... It's kind of a lot of helper functions.
I wonder if we could just do something like:
static void outl_amcc(struct addi_private *devpriv, unsigned int cmd,
unsigned int reg)
{
outl(cmd, devpriv->i_IobaseAmcc + APCI1564_DIGITAL_IP + reg);
}
And then change APCI1564_DIGITAL_IP_INTERRUPT_MODE1 to be:
#define APCI1564_DIGITAL_IP_INTERRUPT_MODE1 (0x4 + 0x4)
The only problem with that would be i_APCI1564_Reset(). Is
i_APCI1564_Reset() buggy? Ian or Hartley might know. Take a look at
other comedi drivers as well to see what they do.
