Subject: [PATCH] ARM: on a generic DT system: do not touch l2x0
Date: Mon,  8 Sep 2014 13:27:41 +0200	[thread overview]
Message-ID: <1410175661-31011-1-git-send-email-linus.walleij@linaro.org> (raw)

Set no bits, mask all bits in the AUX l2x0 register for the
default DT ARM system: if anything needs to be modified, it
should be done using DT bindings.
