Subject: [RFC][PATCH] arm: dts: qcom: apq8064-nexus7: Add pstore support to nexus7
Date: Fri, 23 Sep 2016 17:13:33 -0700 [thread overview]
Message-ID: <1474676013-26106-1-git-send-email-john.stultz@linaro.org> (raw)
Add pstore support for the nexus7. This was useful in debugging
a crash where the cpus were getting stuck with irqs off and
serial output wasn't reliably working.
