x86/PCI: irq and pci_ids patch for additional Intel Cougar Point DeviceIDs
Seth Heasley [Thu, 25 Mar 2010 23:11:37 +0000 (16:11 -0700)]
This patch adds additional LPC Controller DeviceIDs for the Intel Cougar
Point PCH.

The DeviceIDs are defined and referenced as a range of values, the same
way Ibex Peak was implemented.
