-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@...08000 {
- compatible = "mediatek,mt6577-timer";
- reg = <0x10008000 0x80>;
- interrupts = <GIC_SPI 113 IRQ_TYPE_LEVEL_LOW>;
- clocks = <&system_clk>;
