From 1635317facea3094ddf34082cd86797efb1d9f7e Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 6 Sep 2005 13:17:54 +1000 Subject: [PATCH] Separate pci bits out of struct device_node This patch pulls the PCI-related junk out of struct device_node and puts it in a separate structure, struct pci_dn. The device_node now just has a void * pointer in it, which points to a struct pci_dn for nodes that represent PCI devices. It could potentially be used in future for device-specific data for other sorts of devices, such as virtual I/O devices.
