+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 one of the following :
+                       "amlogic,meson-gx-clk-measure" for GX SoCs
+                       "amlogic,meson8-clk-measure" for Meson8 SoCs
+                       "amlogic,meson8b-clk-measure" for Meson8b SoCs
+- reg: base address and size of the Clock Measurer register space.
+
+Example:
+       clock-measure@8758 {
+               compatible = "amlogic,meson-gx-clk-measure";
+               reg = <0x0 0x8758 0x0 0x10>;
+       };
