i've some questions regarding to HW_CLKCTRL_SSPx on the i.MX28, which are not really clear from the reference manual:
What are the exact consequences of changing DIV_FRAC_EN?
Is it necessary to check BUSY or CLKGATE before changing DIV_FRAC_EN?
What does it mean to the DIV field if DIV_FRAC_EN=1?
Is there a relation / constraint between HW_CLKCTRL_SSPx.DIV_FRAC_EN and HW_CLKCTRL_CLKSEQ.BYPASS_SSPx?
