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.
Properties not inherited from the base binding file.

Convey's this node is a GPIO controller
This property is required. |
|
|
Number of items to expect in a GPIO specifier
This property is required. Constant value: |
|
|
Number of GPIOs available on port expander.
Default value: Constant value: |
|
|
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: |
|
|
This is an array of strings defining the names of the GPIO lines
going out of the GPIO controller
|
Deprecated properties not inherited from the base binding file.
(None)
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.

|
Conveys this node is a GPIO hog.
This property is required. |
|
|
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. |
|
|
If this property is set, the GPIO is configured as an input. This property takes
precedence over the output-low and output-high properties.
|
|
|
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.
|
|
|
If this property is set, the GPIO is configured as an output set to logical high.
|
|
|
Optional GPIO line name.
