+* NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
+
+Required properties:
+- compatible: Should be one of the following:
+ - "nxp,sc16is740" for NXP SC16IS740,
+ - "nxp,sc16is741" for NXP SC16IS741,
+ - "nxp,sc16is750" for NXP SC16IS750,
+ - "nxp,sc16is752" for NXP SC16IS752,
+ - "nxp,sc16is760" for NXP SC16IS760,
+ - "nxp,sc16is762" for NXP SC16IS762.
+- reg: I2C address of the SC16IS7xx device.
+- interrupt-parent: The phandle for the interrupt controller that
+ services interrupts for this IC.
+- interrupts: Specifies the interrupt source of the parent interrupt
+ controller. The format of the interrupt specifier depends on the
+ parent interrupt controller.
+- clocks: phandle to the IC source clock.
+
+Optional properties:
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Should be two. The first cell is the GPIO number and
+ the second cell is used to specify the GPIO polarity:
+ 0 = active high,
+ 1 = active low.
+
+Example:
+ sc16is750: sc16is750@51 {
+ compatible = "nxp,sc16is750";
+ reg = <0x51>;
+ clocks = <&clk20m>;
+ interrupt-parent = <&gpio3>;
+ interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
