From a3cabb271ea66739704497102536fb01bb72fe37 Mon Sep 17 00:00:00 2001 From: Uwe Koziolek Date: Thu, 14 Jun 2007 23:40:43 +0200 Subject: libata: PATA-mode fixes for sis_sata Changed PATA handler for PATA-ports used by sata_sis. This patch was originally submitted by Jeff Garzik. Added PCI-ID 1180 for SiS966 Controller in pata_sis. The 1180 mode is fully compatible to other SiS PATA-controller. The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis. 1183 is not working if simply added to pata_sis. This handling fixes issues with SiS968.
