| 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) |
| * "mediatek,mt8365-systimer" for MT8365 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>; |
| }; |
