-MediaTek Timers
----------------
-
-MediaTek SoCs have two different timers on different platforms,
-- 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)

-- reg: Should contain location and length for timer register.
-- clocks: Should contain system clock.
