The I2C controller registers base address is start at 0x14C0_F000 and its address space is 0x2000. The AST2700 I2C controller has one source INTC per bus. I2C buses interrupt are connected to GICINT130_INTC from bit 0 to bit 15. I2C bus 0 is connected to GICINT130_INTC at bit 0. I2C bus 15 is connected to GICINT130_INTC at bit 15.
