Subject: ARM: tegra: Add ACTMON node to Tegra114 device tree
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8577a898af63d2ecfa121bd7270aecf5b65dd23d;p=thirdparty%2Fkernel%2Fstable.git

ARM: tegra: Add ACTMON node to Tegra114 device tree

Add support for ACTMON on Tegra114. This is used to monitor activity from
different components. Based on the collected statistics, the rate at which
the external memory needs to be clocked can be derived.
