1MediaTek Timers 2--------------- 3 4MediaTek SoCs have different timers on different platforms, 5- CPUX (ARM/ARM64 System Timer) 6- GPT (General Purpose Timer) 7- SYST (System Timer) 8 9The proper timer will be selected automatically by driver. 10 11Required properties: 12- compatible should contain: 13 For those SoCs that use GPT 14 * "mediatek,mt2701-timer" for MT2701 compatible timers (GPT) 15 * "mediatek,mt6580-timer" for MT6580 compatible timers (GPT) 16 * "mediatek,mt6582-timer" for MT6582 compatible timers (GPT) 17 * "mediatek,mt6589-timer" for MT6589 compatible timers (GPT) 18 * "mediatek,mt7623-timer" for MT7623 compatible timers (GPT) 19 * "mediatek,mt8127-timer" for MT8127 compatible timers (GPT) 20 * "mediatek,mt8135-timer" for MT8135 compatible timers (GPT) 21 * "mediatek,mt8173-timer" for MT8173 compatible timers (GPT) 22 * "mediatek,mt8516-timer" for MT8516 compatible timers (GPT) 23 * "mediatek,mt6577-timer" for MT6577 and all above compatible timers (GPT) 24 25 For those SoCs that use SYST 26 * "mediatek,mt8183-timer" for MT8183 compatible timers (SYST) 27 * "mediatek,mt8186-timer" for MT8186 compatible timers (SYST) 28 * "mediatek,mt8188-timer" for MT8188 compatible timers (SYST) 29 * "mediatek,mt8192-timer" for MT8192 compatible timers (SYST) 30 * "mediatek,mt8195-timer" for MT8195 compatible timers (SYST) 31 * "mediatek,mt7629-timer" for MT7629 compatible timers (SYST) 32 * "mediatek,mt6765-timer" for MT6765 and all above compatible timers (SYST) 33 34 For those SoCs that use CPUX 35 * "mediatek,mt6795-systimer" for MT6795 compatible timers (CPUX) 36 * "mediatek,mt8365-systimer" for MT8365 compatible timers (CPUX) 37 38- reg: Should contain location and length for timer register. 39- clocks: Should contain system clock. 40 41Examples: 42 43 timer@10008000 { 44 compatible = "mediatek,mt6577-timer"; 45 reg = <0x10008000 0x80>; 46 interrupts = <GIC_SPI 113 IRQ_TYPE_LEVEL_LOW>; 47 clocks = <&system_clk>; 48 }; 49
