From 9143757b57ce549127e1f7bc942e7b61e3b51adf Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Thu, 14 Jan 2016 14:45:20 +0530 Subject: mmc: host: omap_hsmmc: add a verbose print to enable CONFIG_REGULATOR_PBIAS Since v4.3+, CONFIG_REGULATOR_PBIAS should be enabled (for platforms that have PBIAS regulator) in order for MMC1 to work. Add a more verbose print to help enable CONFIG_REGULATOR_PBIAS for users using a olddefconfig or a custom .config.
