Subject: [PATCH v2 1/3] dt-bindings: amlogic: Add Internal Clock Measurer bindings
Date: Wed, 14 Nov 2018 14:16:25 +0100	[thread overview]
Message-ID: <20181114131627.17766-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20181114131627.17766-1-narmstrong@baylibre.com>

The Amlogic Meson GX SoCs embeds a clock measurer IP to measure the internal
clock paths frequencies.

+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@8758 {
+		compatible = "amlogic,meson-gx-clk-measure";
+		reg = <0x0 0x8758 0x0 0x10>;
+	};
