The devices assert a 15 RESET signal if the voltage drops below a preset threshold or upon a manual 16 reset input (MR). The RESET output remains asserted for the factory 17 programmed delay after the voltage return above its threshold or after the 18 manual reset input is released. 19 20 [1] https://www.ti.com/product/TPS3801 21 22properties: 23 compatible: 24 enum: 25 - ti,tps3801 26 27 reset-gpios: 28 maxItems: 1 29 description: Reference to the GPIO connected to the MR pin. 30 31 "#reset-cells": 32 const: 0 33 34required: 35 - compatible 36 - reset-gpios 37 - "#reset-cells" 38 39additionalProperties: false 40 41examples: 42 - | 43 #include <dt-bindings/gpio/gpio.h> 44 reset: reset-controller { 45 compatible = "ti,tps3801"; 46 #reset-cells = <0>; 47 reset-gpios = <&gpio3 2 GPIO_ACTIVE_LOW>; 48 }; 49... 50
