The MAX6959, 15 in comparison to MAX6958, adds input support. Type of the chip can 16 be autodetected via specific register read, and hence the features 17 may be enabled in the driver at run-time, in case they are requested 18 via Device Tree. A given hardware is simple and does not provide 19 any additional pins, such as reset or power enable. 20 21properties: 22 compatible: 23 const: maxim,max6959 24 25 reg: 26 maxItems: 1 27 28required: 29 - compatible 30 - reg 31 32additionalProperties: false 33 34examples: 35 - | 36 i2c { 37 #address-cells = <1>; 38 #size-cells = <0>; 39 40 display-controller@38 { 41 compatible = "maxim,max6959"; 42 reg = <0x38>; 43 }; 44 }; 45
