+description: |
+  Synopsys DesignWare GPIO controllers have a configurable number of ports,
+  each of which are intended to be represented as child nodes with the generic

-* Synopsys DesignWare APB GPIO controller
-
-Required properties:
-- compatible : Should contain "snps,dw-apb-gpio"
-- reg : Address and length of the register set for the device.
-- #address-cells : should be 1 (for addressing port subnodes).
-- #size-cells : should be 0 (port subnodes).
-
-The GPIO controller has a configurable number of ports, each of which are
-represented as child nodes with the following properties:
-
-Required properties:
-- compatible : "snps,dw-apb-gpio-port"
-- 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
-- reg : The integer port index of the port, a single cell.
-
-Optional properties:
-- interrupt-controller : The first port may be configured to be an interrupt
-controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt.  Shall be set to 2.  The first cell defines the interrupt number,
-  the second encodes the triger flags encoded as described in
-  Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-- interrupts : The interrupts to the parent controller raised when GPIOs
-  generate the interrupts. If the controller provides one combined interrupt
-  for all GPIOs, specify a single interrupt. If the controller provides one
-  interrupt for each GPIO, provide a list of interrupts that correspond to each
-  of the GPIO pins. When specifying multiple interrupts, if any are unconnected,
-  use the interrupts-extended property to specify the interrupts and set the
-  interrupt controller handle for unused interrupts to 0.
-- snps,nr-gpios : The number of pins in the port, a single cell.
-- resets : Reset line for the controller.

-Example:
-
