Changes since v1: - DT bindings (Krzysztof) - Moved "allOf:" block after "required:" block - Dropped "type:" from child node in conditional block - Collected tags - Link to v1: https://lore.kernel.org/linux-sunxi/20260227175157.2339758-1-wens@kernel.org/ This series enables the SPI NAND found on the Avaota A1 in Quad SPI mode. The SPI driver already supports Dual SPI and Quad SPI, but the bindings need to be updated to allow it. Patch 1 updates the binding to allow Dual SPI and Quad SPI on the newer SoCs. It also allows describing no TX or no RX available. Patch 2 adds another set of pins for spi0 on the A523 SoC family. This set is used for the SPI NAND on the Avaota A1 board. Patch 3 enables the SPI NAND found on the board. No partition layout is provided at the moment. Please have a look.
