Okay, I've uploaded my latest code:
The port->ops structure has changed. epp_write_block and epp_read_block
now provide a callback, whereas previously they didn't. ('ECP+EPP'
chipsets can DMA EPP.)
They also take callbacks -- compatibility mode can be DMA'd by chipsets
supporting ECP, and for all I know there is a chipset somewhere (or will
be) that DMA's for nibble mode and byte mode.
The file parport_ieee1284_ops.c provides default implementations of the
block-io functions, and the idea is that the architectural drivers provide
better functions, based on what chipset we have.
Something funny's going on with interrupts, in that I don't seem to be
getting any even though I think I should. I suspect the INTEN bit is
getting overwritten somehow.
