- Binding for NXP NX30P6093 moisture detection module
- NX30P6093 is an I2C controlled module and features an input impedance detection
- function, along with OVP protection upto 29V. The impedance detection can detect
- moisture or dust on USB lines and report the same to system to take necessary
- steps to avoid circuit damage to the Type-C port power supply pin.
- =======================
- Supported Properties
- =======================
- - compatible
- Usage: required
- Value type: <string>
- Definition: should be "nxp,nx30p6093".
- - reg
- Usage: required
- Value type: <u32>
- Definition: The device 8-bit I2C address.
- - interrupts
- Usage: required
- Value type: <prop-encoded-array>
- Definition: Moisture detect interrupt specifier.
- - nxp,always-on-detect
- Usage: optional
- Value type: <boolean>
- Definition: If specified, the NX30P6093 is configured to perform
- mositure detection on every detection duty cycle configured
- in "nxp,always-on-tduty-val" property.
- - nxp,always-on-tduty-ms
- Usage: required if "nxp,always-on-detect" specified
- Value type: <u32>
- Definition: The detection duty cycle (Tduty) in milliseconds.
- Supported values are 10, 20, 50, 100, 200, 500, 1000,
- 2000, 3000, 6000, 12000, 30000, 60000, 120000 and 300000.
- If this property is not specified a default value of
- 300000 milliseconds is used.
- - nxp,long-wakeup-sec
- Usage: required if "nxp,always-on-detect" not specified.
- Value type: <u32>
- Definition: A longer time interval in seconds maintained between
- moisture detection events after a previous moisture
- detection event resulted in a good impedance detected
- on USB lines. If this property is not specified a default
- value of 28800 seconds (8 hrs) is used.
- - nxp,short-wakeup-ms
- Usage: required if "nxp,always-on-detect" not specified.
- Value type: <u32>
- Definition: A shorter time interval in milliseconds maintained
- between moisture detection events after a previous
- moisture detection event resulted in a bad impedance
- detected on USB lines. If this property is not specified
- a default value of 180000 milliseconds (3 mins) is used.
- =======
- Example
- =======
- nx30p6093@0 {
- compatible = "nxp,nx30p6093";
- reg = <0x36>;
- interrupt-parent = <&tlmm>;
- interrupts = <5 IRQ_TYPE_NONE>;
- nxp,long-wakeup-sec = <28800>; /* 8 hours */
- nxp,short-wakeup-ms = <180000>; /* 3 mins */
- };
