From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kishon Vijay Abraham I Subject: [PATCH] mmc: host: omap_hsmmc: add a verbose print to enable CONFIG_REGULATOR_PBIAS Date: Thu, 14 Jan 2016 14:45:20 +0530 Message-ID: <1452762920-2588-1-git-send-email-kishon@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Tony Lindgren , Ulf Hansson Cc: pali.rohar@gmail.com, pavel@ucw.cz, sre@debian.org, sre@ring0.de, khilman@kernel.org, aaro.koskinen@iki.fi, ivo.g.dimitrov.75@gmail.com, patrikbachan@gmail.com, linux-omap@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, NeilBrown , linux-mmc@vger.kernel.org, kishon@ti.com, nsekhar@ti.com List-Id: linux-mmc@vger.kernel.org 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.
