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 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Let me know if you want to remove ti,non-removable attribute from > this patch. I dont think its an issue if ti,non-removable and non-removable behave exactly the same. In fact, it will be confusing if they behave differently. I understand there is a need to clean-up the code around no_regulator_off_init, but I am hoping that can be kept separate from moving to a generic binding. The two clean-ups can be done independent of each other.
