I'm sorry, how those 2 drivers can be equivalent?! The pata_winbond driver is for VLB only, sl81c105 was for PCI only -- you certainly want to use pata_sl82c105 (indeed better version of sl82c105 driver).
I was under the impression that with your fixes these drivers (sl82c105 and pata_sl82c105) are functionally equivalent.
They're not yet equivalent. pata_sl82c105 supports all MWDMA modes, sl82c105 still supports only MWDMA2.
Indeed and it seems that IDE core needs ->dma_mode to fix this.
Not really. It just needs the proper DMA timings to be set by adding the missing speedproc() method (and also DMA timings possibly merged with PIO like libata does generally -- except in this driver).
Thanks, Bart
