- - reg: I2C slave address for this device.
- - gpio-controller: Marks the device node as a GPIO controller.
- - #gpio-cells: Should be 2.
- - first cell is the GPIO number
- - second cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>.
- Only the GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
-
-Optional properties:
-
- The I/O expander can detect input state changes, and thus optionally act as
- an interrupt controller. When the expander interrupt line is connected all the
- following properties must be set. For more information please see the
- interrupt controller device tree bindings documentation available at
- Documentation/devicetree/bindings/interrupt-controller/interrupts.txt.
-
- - interrupt-controller: Identifies the node as an interrupt controller.
- - #interrupt-cells: Number of cells to encode an interrupt source, shall be 2.
- - first cell is the pin number
- - second cell is used to specify flags
- - interrupts: Interrupt specifier for the controllers interrupt.
-
-Please refer to gpio.txt in this directory for details of the common GPIO
-bindings used by client devices.

-* Freescale VF610 PORT/GPIO module
-
-The Freescale PORT/GPIO modules are two adjacent modules providing GPIO
-functionality. Each pair serves 32 GPIOs. The VF610 has 5 instances of
-each, and each PORT module has its own interrupt.
-
-Required properties for GPIO node:
-- compatible : Should be "fsl,<soc>-gpio", below is supported list:
- "fsl,vf610-gpio"
- "fsl,imx7ulp-gpio"
-- reg : The first reg tuple represents the PORT module, the second tuple
- the GPIO module.
-- interrupts : Should be the port interrupt shared by all 32 pins.
-- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells : Should be 2. The first cell is the GPIO number.
- The second cell bits[3:0] is used to specify trigger type and level flags:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 8 = active low level-sensitive.
-
-Optional properties:
--clocks: Must contain an entry for each entry in clock-names.
- See common clock-bindings.txt for details.
--clock-names: A list of clock names. For imx7ulp, it must contain
- "gpio", "port".
-
-Note: Each GPIO port should have an alias correctly numbered in "aliases"
-node.
-
-Examples:
-
-aliases {
- gpio0 = &gpio1;
- gpio1 = &gpio2;
-};
