From 24a01453892e0a4a6ad38460541bd0dae9b1837f Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Tue, 30 Jan 2007 20:40:30 +0300 Subject: pata_sl82c105: wrong assumptions about compatible PIO modes Fix the wrong "compatible" PIO mode choices: MWDMA0 has 480 ns cycle while PIO1 only has 383 ns cycle, and MWDMA2 timings matchs those of PIO4 exactly.
