| 89054c7b | 1 | * NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART) |
| 8f4a9120 | 2 | * i2c as bus |
| 89054c7b JR |
3 | |
| 4 | Required 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. | |
| 89054c7b JR |
13 | - interrupts: Should contain the UART interrupt |
| 14 | - clocks: Reference to the IC source clock. | |
| 8650e026 AS |
15 | OR (when there is no clock provider visible to the platform) |
| 16 | - clock-frequency: The source clock frequency for the IC. | |
| 89054c7b JR |
17 | |
| 18 | Optional 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. | |
| 4a9b984f PH |
24 | - irda-mode-ports: An array that lists the indices of the port that |
| 25 | should operate in IrDA mode. | |
| 89054c7b JR |
26 | |
| 27 | Example: | |
| 28 | sc16is750: sc16is750@51 { | |
| 29 | compatible = "nxp,sc16is750"; | |
| 30 | reg = <0x51>; | |
| 31 | clocks = <&clk20m>; | |
| 32 | interrupt-parent = <&gpio3>; | |
| 33 | interrupts = <7 IRQ_TYPE_EDGE_FALLING>; | |
| 34 | gpio-controller; | |
| 35 | #gpio-cells = <2>; | |

49 | - interrupts: Specifies the interrupt source of the parent interrupt |
| 50 | controller. The format of the interrupt specifier depends on the | |
| 51 | parent interrupt controller. | |
| 52 | - clocks: phandle to the IC source clock. | |
