| - compatible should contain: |
| "mediatek,mt2701-wdt", "mediatek,mt6589-wdt": for MT2701 |
| "mediatek,mt2712-wdt": for MT2712 |
| "mediatek,mt6589-wdt": for MT6589 |
| "mediatek,mt6797-wdt", "mediatek,mt6589-wdt": for MT6797 |
| "mediatek,mt7622-wdt", "mediatek,mt6589-wdt": for MT7622 |
| "mediatek,mt7623-wdt", "mediatek,mt6589-wdt": for MT7623 |
| "mediatek,mt7629-wdt", "mediatek,mt6589-wdt": for MT7629 |
| "mediatek,mt7986-wdt", "mediatek,mt6589-wdt": for MT7986 |
| "mediatek,mt8183-wdt": for MT8183 |
| "mediatek,mt8516-wdt", "mediatek,mt6589-wdt": for MT8516 |
| "mediatek,mt8192-wdt": for MT8192 |
| "mediatek,mt8195-wdt", "mediatek,mt6589-wdt": for MT8195 |
| |
| - reg : Specifies base physical address and size of the registers. |
| |
| Optional properties: |
| - interrupts: Watchdog pre-timeout (bark) interrupt. |
| - timeout-sec: contains the watchdog timeout in seconds. |
| - #reset-cells: Should be 1. |

| Example: |
| |
| watchdog: watchdog@10007000 { |
| compatible = "mediatek,mt8183-wdt", |
| "mediatek,mt6589-wdt"; |
| reg = <0 0x10007000 0 0x100>; |
| interrupts = <GIC_SPI 139 IRQ_TYPE_NONE>; |
| timeout-sec = <10>; |
| #reset-cells = <1>; |
| }; |
