+MediaTek Timers
+---------------
+
+MediaTek SoCs have different timers on different platforms,
+- CPUX (ARM/ARM64 System Timer)
+- GPT (General Purpose Timer)
+- SYST (System Timer)
+
+The proper timer will be selected automatically by driver.
+
+Required properties:
+- compatible should contain:
+	For those SoCs that use GPT
+	* "mediatek,mt2701-timer" for MT2701 compatible timers (GPT)
+	* "mediatek,mt6580-timer" for MT6580 compatible timers (GPT)
+	* "mediatek,mt6582-timer" for MT6582 compatible timers (GPT)
+	* "mediatek,mt6589-timer" for MT6589 compatible timers (GPT)
+	* "mediatek,mt7623-timer" for MT7623 compatible timers (GPT)
+	* "mediatek,mt8127-timer" for MT8127 compatible timers (GPT)
+	* "mediatek,mt8135-timer" for MT8135 compatible timers (GPT)
+	* "mediatek,mt8173-timer" for MT8173 compatible timers (GPT)
+	* "mediatek,mt8516-timer" for MT8516 compatible timers (GPT)
+	* "mediatek,mt6577-timer" for MT6577 and all above compatible timers (GPT)
+
+	For those SoCs that use SYST
+	* "mediatek,mt8183-timer" for MT8183 compatible timers (SYST)
+	* "mediatek,mt8186-timer" for MT8186 compatible timers (SYST)
+	* "mediatek,mt8188-timer" for MT8188 compatible timers (SYST)
+	* "mediatek,mt8192-timer" for MT8192 compatible timers (SYST)
+	* "mediatek,mt8195-timer" for MT8195 compatible timers (SYST)
+	* "mediatek,mt7629-timer" for MT7629 compatible timers (SYST)
+	* "mediatek,mt6765-timer" for MT6765 and all above compatible timers (SYST)
+
+	For those SoCs that use CPUX
+	* "mediatek,mt6795-systimer" for MT6795 compatible timers (CPUX)
+
+- reg: Should contain location and length for timer register.
+- clocks: Should contain system clock.
+
+Examples:
+
+	timer@10008000 {
+		compatible = "mediatek,mt6577-timer";
+		reg = <0x10008000 0x80>;
+		interrupts = <GIC_SPI 113 IRQ_TYPE_LEVEL_LOW>;
+		clocks = <&system_clk>;
+	};
