Description

ADP5585 GPIO Controller

Properties

Top level properties

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

Node specific properties

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

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

(None)

Base properties

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 “adi,adp5585-gpio” compatible.

(None)

Child node properties

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.

Specifier cell names

  • gpio cells: pin, flags
