The ecspi-root parent is a mux The mux seems to be missing in the can clock, uart and probably others.I'm looking at IMX6DQRM.pdf 'Rev. B, 07/2011'. I do not see mux for ECSPI_CLK_ROOT as well as other clocks you mentioned. Instead, I can only see divider for these clocks. Can you point out the registers and bits of these muxes you are seeing with these clocks?
No, I can't find them either ;) I must have looked into the wrong manual at that moment. Sorry for the noise.
