+Required properties:
+
+- compatible: should be "nvidia,tegra124-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
+- operating-points: Supported operating points. See ../power/opp.txt for
details.
