Subject: [PATCH 07/10 v3] ARM: mach-shmobile: add fixed voltage regulators to kota2
Date: Tue, 26 Jun 2012 22:32:29 +0000 [thread overview]
Message-ID: <1340749952-8534-8-git-send-email-g.liakhovetski@gmx.de> (raw)
On kota2 provide 1.8V and 3.3V supplies for its SD/MMC-card interfaces
and a dummy regulator for the smsc911x driver.
