The programmable calibration, 20 adjustable conversion time, and averaging function are also built in for 21 more design flexibility. 22 23 Datasheet is available at 24 https://www.richtek.com/assets/product_file/RTQ6056/DSQ6056-00.pdf 25 26properties: 27 compatible: 28 const: richtek,rtq6056 29 30 reg: 31 maxItems: 1 32 33 "#io-channel-cells": 34 const: 1 35 36 shunt-resistor-micro-ohms: 37 description: Shunt IN+/IN- sensing node resistor 38 39required: 40 - compatible 41 - reg 42 - "#io-channel-cells" 43 44additionalProperties: false 45 46examples: 47 - | 48 i2c { 49 #address-cells = <1>; 50 #size-cells = <0>; 51 adc@40 { 52 compatible = "richtek,rtq6056"; 53 reg = <0x40>; 54 #io-channel-cells = <1>; 55 }; 56 }; 57
