From 4e10d12a3d88c88fba3258809aa42d14fd8cf1d1 Mon Sep 17 00:00:00 2001 From: David Shaohua Li Date: Fri, 18 Mar 2005 18:45:35 -0500 Subject: [ACPI] Bind PCI devices with ACPI devices Implement the framework for binding physical devices with ACPI devices. A physical bus like PCI bus should create a 'acpi_bus_type', with: .find_device: For device which has parent such as normal PCI devices. .find_bridge: It's for special devices, such as PCI root bridge or IDE controller. Such devices generally haven't a parent or ->bus. We use the special method to get an ACPI handle.
