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 27Example: 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>; 36 }; 37 38* spi as bus 39 40Required properties: 41- compatible: Should be one of the following: 42 - "nxp,sc16is740" for NXP SC16IS740, 43 - "nxp,sc16is741" for NXP SC16IS741, 44 - "nxp,sc16is750" for NXP SC16IS750, 45 - "nxp,sc16is752" for NXP SC16IS752, 46 - "nxp,sc16is760" for NXP SC16IS760, 47 - "nxp,sc16is762" for NXP SC16IS762. 48- reg: SPI chip select number. 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. 53 54Optional properties: 55- gpio-controller: Marks the device node as a GPIO controller. 56- #gpio-cells: Should be two. The first cell is the GPIO number and 57 the second cell is used to specify the GPIO polarity: 58 0 = active high, 59 1 = active low. 60- irda-mode-ports: An array that lists the indices of the port that 61 should operate in IrDA mode. 62 63Example: 64 sc16is750: sc16is750@0 { 65 compatible = "nxp,sc16is750"; 66 reg = <0>; 67 clocks = <&clk20m>; 68 interrupt-parent = <&gpio3>; 69 interrupts = <7 IRQ_TYPE_EDGE_FALLING>; 70 gpio-controller; 71 #gpio-cells = <2>; 72 }; 73
