Introduce support for SPI-NAND driver of the Airoha NAND Flash Interface found on Airoha ARM EN7581 SoCs. Changes since v3: - rely on devm_kzalloc() to allocate airoha_snand_dev buffers - rely on dev_err_probe() - cosmetic rework Changes since v2: - Fix compilation warnings - Remove interrupt entry in dts since it is not connected so far Changes since v1: - Introduce spi clock dependency Lorenzo Bianconi (3): dt-bindings: spi: airoha: Add YAML schema for SNFI controller arm64: dts: airoha: add EN7581 spi-nand node spi: airoha: add SPI-NAND Flash controller driver .../bindings/spi/airoha,en7581-snand.yaml | 65 + MAINTAINERS | 9 + arch/arm64/boot/dts/airoha/en7581.dtsi | 19 + drivers/spi/Kconfig | 10 + drivers/spi/Makefile | 1 + drivers/spi/spi-airoha-snfi.c | 1140 +++++++++++++++++ 6 files changed, 1244 insertions(+) create mode 100644 Documentation/devicetree/bindings/spi/airoha,en7581-snand.yaml create mode 100644 drivers/spi/spi-airoha-snfi.c -- 2.44.0
