[PATCH v4 0/3] Add add SPI-NAND Flash controller driver for EN7581

[Lorenzo Bianconi <lorenzo@xxxxxxxxxx>]

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
