[PATCH v2 01/10] ARM: OMAP2+: add needs_vmmc to hsmmc_info
Balaji T K

Fri Jun 7 05:14:10 EST 2013
Add needs_vmmc and needs_vmmc_aux to indicate whether regulator is
applicable so that omap_hsmmc can handle deferred probe error
properly for regulators.
Remove the assumption that vmmc_aux regulator to be available only if vmmc is
present. Platforms can have fixed-always-ON regulator for vmmc and/or vmmc_aux
in such cases regulator needed not be specified in board file.
