+ * Intel chipset PIRQ routing control ASL description
+ *
+ * The programming interface is common to most Intel chipsets. But the PRTx
+ * registers may be mapped to different blocks. Some chipsets map them to LPC
+ * device (00:1f:00) PCI configuration space (like TunnelCreek, Quark), while
+ * some newer Atom SoCs (like BayTrail, Braswell) map them to Intel Legacy
+ * Block (ILB) memory space.
+ *
+ * This file defines 8 PCI IRQ link devices which corresponds to 8 PIRQ lines
+ * PIRQ A/B/C/D/E/F/G/H. To incorperate this file, the PRTx registers must be
+ * defined somewhere else in the platform's ASL files.
