Different Phase/Polarity combinations not working for eSPI on P1020RDB

I've successfully implemented the eSPI driver on P1020RDB, but I'm currently facing a problem related to Phase/Polarity combinations. With Polarity low and Phase high, I'm able to successfully transmit data. However, if I use any other combinations, I'm unable to get the correct data transmission. I think I'm setting the registers correctly, and the configuration on the slave is also correct. Is this a hardware limitation? Can anyone point me in the correct direction.
