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]

As Krzysztof has asked, please do provide the changelog, it's
important to track the progress of your series.

Thanks,
