Hi all, This patch implements I2C driver for the SpacemiT K1 SoC, providing basic support for I2C read/write communication which compatible with standard I2C bus specifications. In this version, the driver defaults to use fast-speed-mode and interrupts for transmission, and does not support DMA, high-speed mode, or FIFO. The docs of I2C can be found here, in chapter 16.1 I2C [1] Link: https://developer.spacemit.com/documentation?token=Rn9Kw3iFHirAMgkIpTAcV2Arnkf#part5 [1] Troy Mitchell (2): dt-bindings: i2c: spacemit: add support for K1 SoC i2c: spacemit: add support for SpacemiT K1 SoC .../bindings/i2c/spacemit,k1-i2c.yaml | 51 ++ drivers/i2c/busses/Kconfig | 18 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-k1.c | 658 ++++++++++++++++++ 4 files changed, 728 insertions(+) create mode 100644 Documentation/devicetree/bindings/i2c/spacemit,k1-i2c.yaml create mode 100644 drivers/i2c/busses/i2c-k1.c -- 2.34.1
