+NXP System Counter Module(sys_ctr)
+
+The system counter(sys_ctr) is a programmable system counter which provide=
s
+a shared time base to Cortex A15, A7, A53, A73, etc. it is intended for us=
e in
+applications where the counter is always powered and support multiple,
+unrelated clocks.
+
+Required properties:
+
+- compatible :      should be "nxp,sysctr-timer"
+- reg :             Specifies the base physical address and size of the co=
mapre
+                    frame and the counter control, read & compare.
+- interrupts :      should be the compare frames' interrupt
+- clock-frequency : Specifies the counter clock frequency.
+
+Example:
+
+	system_counter: timer@306a0000 {
+		compatible =3D "nxp,sysctr-timer";
+		reg =3D <0x0 0x306a0000 0x0 0x10000>, /* system-counter-rd base */
+		      <0x0 0x306b0000 0x0 0x10000>, /* system-counter-cmp base */
+		      <0x0 0x306c0000 0x0 0x10000>; /* system-counter-ctrl base */
+		clock-frequency =3D <8000000>;
+		interrupts =3D <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>,
+			     <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
+	};
