+NVIDIA Tegra Activity Monitor
+
+The activity monitor block collects statistics about the behaviour of other
+components in the system. This information can be used to derive the rate at
+which the external memory needs to be clocked in order to serve all requests
+from the monitored clients.
+
+Required properties:
+- compatible: should be "nvidia,tegra<chip>-actmon"
+- reg: offset and length of the register set for the device
+- interrupts: standard interrupt property
+- clocks: Must contain a phandle and clock specifier pair for each entry in
+clock-names. See ../../clock/clock-bindings.txt for details.
+- clock-names: Must include the following entries:
+ - actmon
+ - emc
+- resets: Must contain an entry for each entry in reset-names. See
+../../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - actmon
+
+Example:
+ actmon@6000c800 {
+ compatible = "nvidia,tegra124-actmon";
+ reg = <0x0 0x6000c800 0x0 0x400>;
+ interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&tegra_car TEGRA124_CLK_ACTMON>,
+ <&tegra_car TEGRA124_CLK_EMC>;
+ clock-names = "actmon", "emc";
+ resets = <&tegra_car 119>;
+ reset-names = "actmon";
+ };
