From: Uwe Koziolek Date: Thu, 14 Jun 2007 21:40:43 +0000 (+0200) Subject: libata: PATA-mode fixes for sis_sata X-Git-Tag: v2.6.22~48^2 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a3cabb271ea66739704497102536fb01bb72fe37;p=linux-2.6 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.
