This patch set adds LPC BIOS Post code (BPC) support for the Nuvoton NPCM Baseboard Management Controller (BMC). Nuvoton BMC NPCM LPC BIOS Post Code (BPC) monitoring two configurable I/O addresses written by the host on the Low Pin Count (LPC) bus, the capture data stored in 128-word FIFO. NPCM BPC can support capture double words. The NPCM7xx BPC driver tested on NPCM750 evaluation board. NPCM BPC driver upstream process start few months ago on misc folder http://lkml.iu.edu/hypermail/linux/kernel/1904.2/00412.html The NPCM LPC BPC is similar to Aspeed LPC snoop, last kernel 5.0.2 Aspeed LPC snoop driver moved from misc folder to soc folder, so it seems NPCM BPC dirver should upstream to soc as well. https://lkml.org/lkml/2019/4/22/377 I have created common lpc-snoop documentation for both Nuvoton and Aspeed drivers as Andrew suggested. Andrew Jeffery: https://patchwork.kernel.org/patch/10506269/ I add Andrew and Rob reviewed signature because they already reviewed and signed the lpc-snoop documentation in the misc folder https://lkml.org/lkml/2019/4/29/998 Tomer Maimon (2): dt-binding: soc: Add common LPC snoop documentation soc: nuvoton: add NPCM LPC BPC driver .../devicetree/bindings/soc/lpc/lpc-snoop.txt | 27 ++ drivers/soc/Kconfig | 1 + drivers/soc/Makefile | 1 + drivers/soc/nuvoton/Kconfig | 16 + drivers/soc/nuvoton/Makefile | 2 + drivers/soc/nuvoton/npcm-lpc-bpc-snoop.c | 387 ++++++++++++++++++ 6 files changed, 434 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/lpc/lpc-snoop.txt create mode 100644 drivers/soc/nuvoton/Kconfig create mode 100644 drivers/soc/nuvoton/Makefile create mode 100644 drivers/soc/nuvoton/npcm-lpc-bpc-snoop.c -- 2.18.0
