-GPIO Driver for XRA1403 16-BIT GPIO Expander With Reset Input from EXAR
-
-The XRA1403 is an 16-bit GPIO expander with an SPI interface. Features available:
-	- Individually programmable inputs:
-		- Internal pull-up resistors
-		- Polarity inversion
-		- Individual interrupt enable
-		- Rising edge and/or Falling edge interrupt
-		- Input filter
-	- Individually programmable outputs
-		- Output Level Control
-		- Output Three-State Control
-
-Properties
-----------
-Check documentation for SPI and GPIO controllers regarding properties needed to configure the node.
-
-	- compatible = "exar,xra1403".
-	- reg - SPI id of the device.
-	- gpio-controller - marks the node as gpio.
-	- #gpio-cells - should be two where the first cell is the pin number
-		and the second one is used for optional parameters.
-
-Optional properties:
--------------------
-	- reset-gpios: in case available used to control the device reset line.
-	- interrupt-controller - marks the node as interrupt controller.
-	- #interrupt-cells - should be two and represents the number of cells
-		needed to encode interrupt source.
-
-Example
---------
-
-	gpioxra0: gpio@2 {
-		compatible = "exar,xra1403";
-		reg = <2>;
-
-		gpio-controller;
-		#gpio-cells = <2>;
-
-		interrupt-controller;
-		#interrupt-cells = <2>;
-
-		reset-gpios = <&gpio3 6 GPIO_ACTIVE_LOW>;
-		spi-max-frequency = <1000000>;
