* 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. 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. - 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>; };
