If it is NOT good to disabling those peripheral devices' clock in i.MX7ULP's clock driver, then we have to change the core framework to disable clock explicitly if the CLK_SET_RATE_GATE/CLK_SET_PARENT_GATE is present, most likely it will impact other platforms I think, so the most safe way is just to do it inside our i.MX7ULP composite clock driver. What do you think?

Just tested your patch against 5.3 and mmc card can be detected with it.

Please note that I had to manually add:
#include <linux/io.h>

so that it can build.

I agree we need to come to a solution for this.

Stephen, please let us know your thoughts.

Thanks
