I used a serial flash on IMX7D target board, when the spi clcok is 29M, It works well, but when I change it to 84M, read data error,IF I write data at 84M and read it at 29M, it is ok. But if 84M write data and 84M read data, It faild. So ,if I change the spi clock frequence, what  othre parameters in qspi controller should I change at the same time ?
