Only basic single- and dual-bit transfers are supported for now, with DMA mode support yet to come. v2: - Drop clock name - Make driver callbacks static, as reported by the bot - Syntax fixes in DT binding docs Bert Vermeulen (3): dt-bindings: arm: airoha: Add documentation for Airoha SPI controller spi: Add support for the Airoha EN7523 SoC SPI controller ARM: dts: en7523: Add SPI node .../bindings/spi/airoha,en7523-spi.yaml | 45 +++ arch/arm/boot/dts/en7523-evb.dts | 20 ++ arch/arm/boot/dts/en7523.dtsi | 10 + drivers/spi/Kconfig | 7 + drivers/spi/Makefile | 1 + drivers/spi/spi-en7523.c | 305 ++++++++++++++++++ 6 files changed, 388 insertions(+) create mode 100644 Documentation/devicetree/bindings/spi/airoha,en7523-spi.yaml create mode 100644 drivers/spi/spi-en7523.c Reviewed-by: Rob Herring
