Hi, v4 patch back to only raw NAND controller driver instead of MFD, raw NAND and SPI driver. This is based on MFD maintainer, Lee Jones comments: MFD is for registering child devices of chips which offer genuine cross-subsystem functionality. It is not designed for mode selecting, or as a place to shove shared code just because a better location doesn't appear to exist. v3 patch is to rename the title of SPI controller driver. "Patch Macronix SPI controller driver according to MX25F0A MFD driver" v2s patches is to support Macronix MX25F0A MFD driver for raw nand and spi controller which is separated form previous patchset: https://patchwork.kernel.org/patch/10874679/ thanks for your review. best regards, Mason Mason Yang (2): mtd: rawnand: Add Macronix Raw NAND controller dt-bindings: mtd: Document Macronix raw NAND controller bindings .../devicetree/bindings/mtd/mxic-nand.txt | 26 + drivers/mtd/nand/raw/Kconfig | 6 + drivers/mtd/nand/raw/Makefile | 1 + drivers/mtd/nand/raw/mxic_nand.c | 551 +++++++++++++++++++++ 4 files changed, 584 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/mxic-nand.txt create mode 100644 drivers/mtd/nand/raw/mxic_nand.c -- 1.9.1
