| 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>; |
| }; |
