in past days ,i haved a problem about mcspi with touchscreen,i find the mcspi->ick is different.
in normal status: the mcspi->ick = 166000000 ,the kernel and 2010-06-version uboot,
error status:the mcspo->ick = 83000000,the same kernel but 2010-12-version uboot.
so i want to try to change ,where i can do it ,in uboot or in linux kernel driver or linux clock_init ,please give some advices ,thank you .why uboot can effect linux kernel clock???thank you ！！！！
