-NXP System Counter Module(sys_ctr)
-
-The system counter(sys_ctr) is a programmable system counter which provides
-a shared time base to Cortex A15, A7, A53, A73, etc. it is intended for use in
-applications where the counter is always powered and support multiple,
-unrelated clocks. The compare frame inside can be used for timer purpose.
-
-Required properties:
-
-- compatible :      should be "nxp,sysctr-timer"
-- reg :             Specifies the base physical address and size of the comapre
-                    frame and the counter control, read & compare.
-- interrupts :      should be the first compare frames' interrupt
-- clocks : 	    Specifies the counter clock.
-- clock-names: 	    Specifies the clock's name of this module
-
-Example:
-
-	system_counter: timer@306a0000 {
-		compatible = "nxp,sysctr-timer";
-		reg = <0x306a0000 0x20000>;/* system-counter-rd & compare */
-		clocks = <&clk_8m>;
-		clock-names = "per";
-		interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
-	};
