I'm not sure if this got merged, but it might be good to use the standard attribute instead.
Hi Benoit, Those patches are not merged yet, standard attribute is good, but few cleanups are needed before ti,non-removable can be replaced by standard non-removable, no_regulator_off_init flag set under ti,non-removable is needed to detect eMMC during boot on OMAP4 devices to keep regulator ON during init. Given that eMMC on dra7-evm is powered by always ON regulator, ti,non-removable and standard attribute will behave same way. Let me know if you want to remove ti,non-removable attribute from this patch.
Regards, Benoit
