Vendor: Intel Corporation

Description

Intel GPIO node

Properties

Properties not inherited from the base binding file.

Name

Type

Details

group-index

int

Group number for this GPIO entry

ngpios

int

Number of pins for this GPIO entry

This property is required.

Default value: 32

pin-offset

int

Pin offset of this GPIO entry

This property is required.

#gpio-cells

int

Number of items to expect in a GPIO specifier

This property is required.

Constant value: 2

gpio-controller

boolean

Convey's this node is a GPIO controller

This property is required.

gpio-reserved-ranges

array

If not all the GPIOs at offsets 0...N-1 are usable for ngpios = <N>, then
this property contains an additional set of tuples which specify which GPIOs
are unusable. This property indicates the start and size of the GPIOs
that can't be used.

For example, setting "gpio-reserved-ranges = <3 2>, <10 1>;" means that
GPIO offsets 3, 4, and 10 are not usable, even if ngpios = <18>.

gpio-line-names

string-array

This is an array of strings defining the names of the GPIO lines
going out of the GPIO controller

Specifier cell names

  • gpio cells: pin, flags
