Sekhar just posted a series to replace that with a non-TI attribute:
non-removable.
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
