Subject: [PATCH 17/22] mmc: omap_hsmmc: ensure pbias configuration is always done
Date: Thu,  5 May 2011 14:51:17 +0300	[thread overview]
Message-ID: <1304596282-4095-18-git-send-email-adrian.hunter@nokia.com> (raw)
In-Reply-To: <1304596282-4095-1-git-send-email-adrian.hunter@nokia.com>

Go through the driver's set_power() functions rather than
calling regulator_enable/disable() directly because otherwise
pbias configuration for MMC1 is not done.
