here, instead handle that from the
.set_ios function. This complete code chunk must also be moved prior
to mmc_add_host above.
When enabling/disabling the regulator from the .set_ios, I suppose you
want to use mmc_regulator_set_ocr API instead.

code for this is already, nomadik and omap
for example. I think typically clocks, pins and if there are a power
domain regulator for the controller, those should be handled through
runtime PM to save power at request inactivity.

certainly appreciate some advise from you at

That would be kind of OK, if the driver's .suspend_late() only invoked its own
.runtime_suspend(), what you did below.
But, in the Ulf's approach the driver calls .runtime_suspend() from
its *subsystem* in the hope that it will all work out properly (or
