|  | * 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: Should contain the UART interrupt | 
|  | - clocks: Reference 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>; | 
|  | }; |
