Subject: [PATCH 1/2] ARM: tegra: tamonten: add the base board regulators
Date: Thu, 12 Jun 2014 17:11:24 +0200 [thread overview]
Message-ID: <1402585885-28247-1-git-send-email-alban.bedel@avionic-design.de> (raw)
Currently the Tamonten DTS define a fixed regulator for the 5V supply.
However this regulator is in fact on the base board. Fix this by
properly defining the regulators found on the base boards.
