Kailua uses div2 because the CXO input gets used divided by 2 by PHYs and divided by 4 for GCC/DISPCC/... This is why we introduced a div2 clock in DT used to feed GCC/DISPCC/... Neil
Yes div4 is the correct divider only for sm4450 as CXO input get directly divided by 4 only. This is someting similiar to sm8450 and there is no in between div2 divider like Kailua.
