| * 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. |
| - 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>; |
| }; |
| |
| * spi 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: SPI chip select number. |
| - interrupt-parent: The phandle for the interrupt controller that |
| services interrupts for this IC. |
| - interrupts: Specifies the interrupt source of the parent interrupt |
| controller. The format of the interrupt specifier depends on the |
| parent interrupt controller. |
| - clocks: phandle 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@0 { |
| compatible = "nxp,sc16is750"; |
| reg = <0>; |
| clocks = <&clk20m>; |
| interrupt-parent = <&gpio3>; |
| interrupts = <7 IRQ_TYPE_EDGE_FALLING>; |
| gpio-controller; |
| #gpio-cells = <2>; |
| }; |
