-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,sx1501q",
- "semtech,sx1502q",
- "semtech,sx1503q",
- "semtech,sx1504q",
- "semtech,sx1505q",
- "semtech,sx1506q",
- "semtech,sx1507q",
- "semtech,sx1508q",
- "semtech,sx1509q".
-
-- 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 :
-- 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 sx1507q, 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 sx1507q, 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;
- };
- };
