|
|
|
|
- compatible should contain:
|
|
"mediatek,mt2701-wdt", "mediatek,mt6589-wdt": for MT2701
|
|
"mediatek,mt2712-wdt": for MT2712
|
|
"mediatek,mt6582-wdt", "mediatek,mt6589-wdt": for MT6582
|
|
"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:
|
|
- mediatek,disable-extrst: disable send output reset signal
|
|
- 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";
|
|
mediatek,disable-extrst;
|
|
reg = <0 0x10007000 0 0x100>;
|
|
interrupts = <GIC_SPI 139 IRQ_TYPE_NONE>;
|
|
timeout-sec = <10>;
|
|
#reset-cells = <1>;
|
|
};
