The SPISG is a communication-oriented SPI controller from Amlogic,supporting three operation modes: PIO, block DMA, and scatter-gather DMA. Add the drivers and device tree bindings corresponding to the SPISG. Signed-off-by: Xianwei Zhao --- Changes in v2: - Use regmap to operation register and drop bitfied define. - Use "SPISG" prefix intead of "SPICC", and declare clock div table in the spisg_device. - Delete other power operation functions except for runtime_supspend and runtime_resume. - Fix some format corrections. - Link to v1: https://lore.kernel.org/r/20250604-spisg-v1-0-5893dbe9d953@amlogic.com --- Sunny Luo (2): dt-bindings: spi: Add binding document of Amlogic SPISG controller spi: Add Amlogic SPISG driver Xianwei Zhao (1): MAINTAINERS: Add an entry for Amlogic spi driver .../devicetree/bindings/spi/amlogic,a4-spisg.yaml | 55 ++ MAINTAINERS | 9 + drivers/spi/Kconfig | 9 + drivers/spi/Makefile | 1 + drivers/spi/spi-amlogic-spisg.c | 878 +++++++++++++++++++++ 5 files changed, 952 insertions(+) --- base-commit: bd30b995df8fd053e13d10f78dbc7b2fa5ed1aae change-id: 20250603-spisg-78f21682ebac Best regards, -- Xianwei Zhao
