nuvoton,nct38xx-gpio-alert

Description

Nuvoton NCT38XX series I2C-based GPIO expander alert handler

Example:
  nct3807_alert_1 {
    compatible = "nuvoton,nct38xx-gpio-alert";
    irq-gpios = <&gpiod 4 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;
    nct38xx-dev = <&nct3808_0_P1 &nct3808_0_P2>;
    label = "NCT3808_ALERT_0";
  };

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`irq-gpios`	`phandle-array`	Interrupt GPIO pin This property is required.
`nct38xx-dev`	`phandles`	NCT38XX devices which alert are handled by this alert handler. This property is required.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nuvoton,nct38xx-gpio-alert” compatible.

Name	Type	Details
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) This property is required. See Important properties for more information.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
