1 * NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
3 Required properties:
4 - compatible: Should be one of the following:
5   - "nxp,sc16is740" for NXP SC16IS740,
6   - "nxp,sc16is741" for NXP SC16IS741,
7   - "nxp,sc16is750" for NXP SC16IS750,
8   - "nxp,sc16is752" for NXP SC16IS752,
9   - "nxp,sc16is760" for NXP SC16IS760,
10   - "nxp,sc16is762" for NXP SC16IS762.
11 - reg: I2C address of the SC16IS7xx device.
12 - interrupt-parent: The phandle for the interrupt controller that
13   services interrupts for this IC.
14 - interrupts: Should contain the UART interrupt
15 - clocks: Reference to the IC source clock.
17 Optional properties:
18 - gpio-controller: Marks the device node as a GPIO controller.
19 - #gpio-cells: Should be two. The first cell is the GPIO number and
20   the second cell is used to specify the GPIO polarity:
21     0 = active high,
22     1 = active low.
24 Example:
25         sc16is750: sc16is750@51 {
26                 compatible = "nxp,sc16is750";
27                 reg = <0x51>;
28                 clocks = <&clk20m>;
29                 interrupt-parent = <&gpio3>;
30                 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
31                 gpio-controller;
32                 #gpio-cells = <2>;
33         };
