+Amlogic Internal Clock Measurer
+===============================
+
+The Amlogic SoCs contains an IP to measure the internal clocks.
+The precision is multiple of MHz, useful to debug the clock states.
+
+Required properties:
+- compatible: Shall contain "amlogic,meson-gx-clk-measure"
+- reg: base address and size of the Clock Measurer register space.
+
+Example:
+ clock-measure@...8 {
+ compatible = "amlogic,meson-gx-clk-measure";
+ reg = <0x0 0x8758 0x0 0x10>;
+ };
