1* NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
2* i2c as bus
3
4Required properties:
5- compatible: Should be one of the following:
6  - "nxp,sc16is740" for NXP SC16IS740,
7  - "nxp,sc16is741" for NXP SC16IS741,
8  - "nxp,sc16is750" for NXP SC16IS750,
9  - "nxp,sc16is752" for NXP SC16IS752,
10  - "nxp,sc16is760" for NXP SC16IS760,
11  - "nxp,sc16is762" for NXP SC16IS762.
12- reg: I2C address of the SC16IS7xx device.
13- interrupts: Should contain the UART interrupt
14- clocks: Reference to the IC source clock.
15	OR (when there is no clock provider visible to the platform)
16- clock-frequency: The source clock frequency for the IC.
17
18Optional properties:
19- gpio-controller: Marks the device node as a GPIO controller.
20- #gpio-cells: Should be two. The first cell is the GPIO number and
21  the second cell is used to specify the GPIO polarity:
22    0 = active high,
23    1 = active low.
24- irda-mode-ports: An array that lists the indices of the port that
25		   should operate in IrDA mode.
26- nxp,modem-control-line-ports: An array that lists the indices of the port that
27				should have shared GPIO lines configured as
28				modem control lines.
