Hi all:

This patch set describes the I2C controller integrated the
Loongson-2K0300 chip.

It has a significantly different design from the previous I2C
controller(i2c-ls2x), such as support for master-slave transfer mode,
and  DMA transfers (implementation in progress), etc. Therefore, we try
to name it i2c-ls2x-v2.

Thanks.
