It supports four chip selects, and direct (memory-mapped) access to 16 MiB per chip. Larger flash chips can be accessed by software-defined SPI transfers. The existing NPCM7xx FIU driver is sufficitently incompatible with the WPCM450 FIU that I decided to write a new driver. Changelog for v2: - Dropped the patches which have been applied in the meantime, leaving only three out of eight - Changed the binding to require both items in the reg property, because there is no need to keep the second item optional, suggested by Krzysztof Kozlowski - Various other cleanups suggested by Krzysztof Kozlowski and the kernel test robot Jonathan Jonathan Neuschäfer (3): dt-bindings: spi: Add Nuvoton WPCM450 Flash Interface Unit (FIU) spi: wpcm-fiu: Add driver for Nuvoton WPCM450 Flash Interface Unit (FIU) spi: wpcm-fiu: Add direct map support .../bindings/spi/nuvoton,wpcm450-fiu.yaml | 66 +++ drivers/spi/Kconfig | 11 + drivers/spi/Makefile | 1 + drivers/spi/spi-wpcm-fiu.c | 508 ++++++++++++++++++ 4 files changed, 586 insertions(+) create mode 100644 Documentation/devicetree/bindings/spi/nuvoton,wpcm450-fiu.yaml create mode 100644 drivers/spi/spi-wpcm-fiu.c -- 2.35.1
