Subject: [PATCH resend 0/4] spi: add support for Mediatek SPI-NAND controller
Date: Sun,  3 Apr 2022 21:14:49 +0800	[thread overview]
Message-ID: <20220403131453.1269229-1-gch981213@gmail.com> (raw)

Mediatek has an extended version of their NAND Flash Interface which
has a SPI-NAND mode. In this mode, the controller can perform 1-bit
spi-mem ops for up-to 0xa0 bytes and typical SPI-NAND single, dual
and quad IO page cache ops with 2-byte address. Additionally, the
page cache ops can be performed with ECC and auto data formatting
using the ECC engine of the controller.

This patchset implements support of this mode as a separated SPI-MEM
driver with piplined ECC engine.

  mtd: nand: make mtk_ecc.c a separated module
  spi: add driver for MTK SPI NAND Flash Interface
  dt-bindings: spi: add binding doc for spi-mtk-snfi
