+SEMTECH SX150x GPIO expander bindings
+
+Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
+../interrupt-controller/interrupts.txt for generic information regarding
+pin controller, GPIO, and interrupt bindings.
+
+Required properties:
+- compatible: should be one of :
+			"semtech,sx1506q",
+			"semtech,sx1508q",
+			"semtech,sx1509q",
+			"semtech,sx1502q".
+
+- reg: The I2C slave address for this device.
+
+- #gpio-cells: Should be 2. The first cell is the GPIO number and the
+		second cell is used to specify optional parameters:
+		bit 0: polarity (0: normal, 1: inverted)
+
+- gpio-controller: Marks the device as a GPIO controller.
+
+Optional properties :
+- interrupt-parent: phandle of the parent interrupt controller.
+
+- interrupts: Interrupt specifier for the controllers interrupt.
+
+- interrupt-controller: Marks the device as a interrupt controller.
+
+- semtech,probe-reset: Will trigger a reset of the GPIO expander on probe,
+		only for sx1508q and sx1509q
+
+The GPIO expander can optionally be used as an interrupt controller, in
+which case it uses the default two cell specifier.
+
+Required properties for pin configuration sub-nodes:
+ - pins: List of pins to which the configuration applies.
+
+Optional properties for pin configuration sub-nodes:
+----------------------------------------------------
+ - bias-disable: disable any pin bias, except the OSCIO pin
+ - bias-pull-up: pull up the pin, except the OSCIO pin
+ - bias-pull-down: pull down the pin, except the OSCIO pin
+ - bias-pull-pin-default: use pin-default pull state, except the OSCIO pin
+ - drive-push-pull: drive actively high and low
+ - drive-open-drain: drive with open drain only for sx1508q and sx1509q and except the OSCIO pin
+ - output-low: set the pin to output mode with low level
+ - output-high: set the pin to output mode with high level
+
+Example:
+
+	i2c0gpio-expander@20{
+		#gpio-cells = <2>;
+		#interrupt-cells = <2>;
+		compatible = "semtech,sx1506q";
+		reg = <0x20>;
+		interrupt-parent = <&gpio_1>;
+		interrupts = <16 0>;
+
+		gpio-controller;
+		interrupt-controller;
+
+		pinctrl-names = "default";
+		pinctrl-0 = <&gpio1_cfg_pins>;
+
+		gpio1_cfg_pins: gpio1-cfg {
+			pins = "gpio1";
+			bias-pull-up;
+		};
