I'm using an imx6 conected to a fpga by I2C and i notice a problem. If I read several bytes from fpga, it does not work but if I add a delay in imx-i2c driver between the interrupt of receive data and the read of  I2C_I2DR, I read correct data. Do the interrupt occurs after or before I2C_I2DR register is loaded with received data ?
