Description

ADP5585 GPIO Controller

These property descriptions apply to “adi,adp5585-gpio” nodes themselves. This page also describes child node properties in the following sections.

Properties not inherited from the base binding file.

Name	Type	Details
`#gpio-cells`	`int`	Number of items to expect in a GPIO specifier This property is required. Constant value: `2`
`ngpios`	`int`	Number of GPIOs available on port expander. Default value: `32` Constant value: `13`
`gpio-reserved-ranges`	`array`	Ranges of GPIOs reserved unavailable on port expander. The ADP5585 has 10 GPIO lines divided in 2 groups. GPIO number 5, 6, 7 is reserved. That's to say, GPIO R0~R4 occupy line number 0~4, GPIO C0~C4 occupy line number 8~12. This property is required. Constant value: `[5, 3]`
`gpio-controller`	`boolean`	Convey's this node is a GPIO controller This property is required.
`gpio-line-names`	`string-array`	This is an array of strings defining the names of the GPIO lines going out of the GPIO controller

Name	Type	Details
`gpio-hog`	`boolean`	Conveys this node is a GPIO hog. This property is required.
`gpios`	`array`	This is an array of GPIO specifiers (e.g. pin, flags) to be hogged. The number of array entries must be an integer multiple of the number of GPIO specifier cells for the parent GPIO controller. This property is required.
`input`	`boolean`	If this property is set, the GPIO is configured as an input. This property takes precedence over the output-low and output-high properties.
`output-low`	`boolean`	If this property is set, the GPIO is configured as an output set to logical low. This property takes precedence over the output-high property.
`output-high`	`boolean`	If this property is set, the GPIO is configured as an output set to logical high.
`line-name`	`string`	Optional GPIO line name.
