The 24 integrated ADC channels (AMONx) monitor the power supply 16 voltage, current, and temperature. Of the 84 GPIO pins, 8 can be used as 17 digital monitors (DMONx), 32 to enable the power supply (ENx), 24 for 18 margining (MARx), 16 for logical GPO, and 32 GPIs for cascading, and system 19 function. 20 21 http://focus.ti.com/lit/ds/symlink/ucd90320.pdf 22 23properties: 24 compatible: 25 enum: 26 - ti,ucd90320 27 28 reg: 29 maxItems: 1 30 31required: 32 - compatible 33 - reg 34 35additionalProperties: false 36 37examples: 38 - | 39 i2c { 40 #address-cells = <1>; 41 #size-cells = <0>; 42 43 ucd90320@11 { 44 compatible = "ti,ucd90320"; 45 reg = <0x11>; 46 }; 47 }; 48
