[PATCH 1/3] PCI: Add hide_device support to pci subsystem.

2013-07-03 Thread Haicheng Li
With more and more SOCs having pci device integrated into chip (e.g. Intel Atom series), it's useful to add an interface to cleanly hide pci devices from pci device scanning, which is because: 1. phone or tablet OEMs may choose disabling some pci device in the SOC, such as camera ISP in Intel A
