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 16Optional properties: 17- gpio-controller: Marks the device node as a GPIO controller. 18- #gpio-cells: Should be two. The first cell is the GPIO number and 19 the second cell is used to specify the GPIO polarity: 20 0 = active high, 21 1 = active low. 22 23Example: 24 sc16is750: sc16is750@51 { 25 compatible = "nxp,sc16is750"; 26 reg = <0x51>; 27 clocks = <&clk20m>; 28 interrupt-parent = <&gpio3>; 29 interrupts = <7 IRQ_TYPE_EDGE_FALLING>; 30 gpio-controller; 31 #gpio-cells = <2>; 32 }; 33 34* spi as bus 35 36Required properties: 37- compatible: Should be one of the following: 38 - "nxp,sc16is740" for NXP SC16IS740, 39 - "nxp,sc16is741" for NXP SC16IS741, 40 - "nxp,sc16is750" for NXP SC16IS750, 41 - "nxp,sc16is752" for NXP SC16IS752, 42 - "nxp,sc16is760" for NXP SC16IS760, 43 - "nxp,sc16is762" for NXP SC16IS762. 44- reg: SPI chip select number. 45- interrupts: Specifies the interrupt source of the parent interrupt 46 controller. The format of the interrupt specifier depends on the 47 parent interrupt controller. 48- clocks: phandle to the IC source clock. 49 50Optional properties: 51- gpio-controller: Marks the device node as a GPIO controller. 52- #gpio-cells: Should be two. The first cell is the GPIO number and 53 the second cell is used to specify the GPIO polarity: 54 0 = active high, 55 1 = active low. 56 57Example: 58 sc16is750: sc16is750@0 { 59 compatible = "nxp,sc16is750"; 60 reg = <0>; 61 clocks = <&clk20m>; 62 interrupt-parent = <&gpio3>; 63 interrupts = <7 IRQ_TYPE_EDGE_FALLING>; 64 gpio-controller; 65 #gpio-cells = <2>; 66 }; 67
