+Nuvoton NPCM7xx LPC BPC interface
+
+Nuvoton BMC NPCM7xx BIOS Post Code (BPC) monitoring two
+configurable I/O addresses written by the host on the
+Low Pin Count (LPC) bus, the capure data stored in 128-word FIFO.
+
+NPCM7xx BPC supports capture double words, when using capture
+double word only I/O address 1 is monitored.
+
+Required properties for lpc_bpc node
+- compatible : "nuvoton,npcm750-lpc-bpc" for Poleg NPCM7XX.
+- reg : specifies physical base address and size of the registers.
+- interrupts : contain the LPC BPC with flags for falling edge.
+- monitor-ports : contain monitor I/O addresses, at least one monitor I/O
+ address required
+
+Optional property for lpc_bpc node
+- bpc-en-dwcapture : enable capture double words support.
+
+Example:
+ lpc_bpc: lpc-bpc@f0007040 {
+ compatible = "nuvoton,npcm7xx-lpc-bpc";
+ reg = <0xf0007040 0x14>;
+ monitor-ports = <0x80>;
+ interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>;
+ };
