This node is intended to allow the host to read and 16 control the Type C ports. The node for this device should be under a 17 cros-ec node like google,cros-ec-spi. 18 19properties: 20 compatible: 21 const: google,cros-ec-typec 22 23 '#address-cells': 24 const: 1 25 26 '#size-cells': 27 const: 0 28 29patternProperties: 30 '^connector@[0-9a-f]+$': 31 $ref: /schemas/connector/usb-connector.yaml# 32 unevaluatedProperties: false 33 properties: 34 reg: 35 maxItems: 1 36 37required: 38 - compatible 39 40additionalProperties: false 41 42examples: 43 - |+ 44 spi { 45 #address-cells = <1>; 46 #size-cells = <0>; 47 48 cros_ec: ec@0 { 49 compatible = "google,cros-ec-spi"; 50 reg = <0>; 51 interrupts = <35 0>; 52 53 typec { 54 compatible = "google,cros-ec-typec"; 55 56 #address-cells = <1>; 57 #size-cells = <0>; 58 59 connector@0 { 60 compatible = "usb-c-connector"; 61 reg = <0>; 62 power-role = "dual"; 63 data-role = "dual"; 64 try-power-role = "source"; 65 }; 66 }; 67 }; 68 }; 69
