I'm sorry to cause you confusion.
 1) spi: imx: add 16/32 bits per word support for slave mode and B 
 2) spi: imx: add a check for speed_hz before calculating the clock
These two patch above are two independent patches.
Now 2) is no longer needed, I just sent 3) to fix the real problem.
 3) spi: imx: remove CLK calculation and divider in slave mode

Thank you very much!
