From 11e872a3e1e93ba00e5ec04a74c4d2fe3e14e708 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 13 Oct 2011 18:11:29 +0200 Subject: [PATCH] pata_it8213: add UDMA100 and UDMA133 support Fixes IDE -> libata regression. IDE's it8213 host driver has been supporting those modes (per official documentation) since the initial driver's merge on Feb 7 2007 (commit 9c6712c0 "ide: add it8213 IDE driver").
