| * NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART) |
| * i2c as bus |
| |
| 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. |
| - interrupts: Should contain the UART interrupt |
| - clocks: Reference to the IC source clock. |
| OR (when there is no clock provider visible to the platform) |
| - clock-frequency: The source clock frequency for the IC. |
| |
| 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. |
| - irda-mode-ports: An array that lists the indices of the port that |
| should operate in IrDA mode. |
| - nxp,modem-control-line-ports: An array that lists the indices of the port that |
| should have shared GPIO lines configured as |
| modem control lines. |
| |
| Example: |
| sc16is750: sc16is750@51 { |
| compatible = "nxp,sc16is750"; |
| reg = <0x51>; |
| clocks = <&clk20m>; |

| compatible = "nxp,sc16is752"; |
| reg = <0x53>; |
| clocks = <&clk20m>; |
| interrupt-parent = <&gpio3>; |
| interrupts = <7 IRQ_TYPE_EDGE_FALLING>; |
| nxp,modem-control-line-ports = <1>; /* Port 1 as modem control lines */ |
| gpio-controller; /* Port 0 as GPIOs */ |
| #gpio-cells = <2>; |

| interrupt-parent = <&gpio3>; |
| interrupts = <7 IRQ_TYPE_EDGE_FALLING>; |
| nxp,modem-control-line-ports = <0 1>; /* Ports 0 and 1 as modem control lines */ |
| }; |

| - "nxp,sc16is762" for NXP SC16IS762. |
| - reg: SPI chip select number. |
