0001 * NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
0002 * i2c as bus
0003
0004 Required properties:
0005 - compatible: Should be one of the following:
0006 - "nxp,sc16is740" for NXP SC16IS740,
0007 - "nxp,sc16is741" for NXP SC16IS741,
0008 - "nxp,sc16is750" for NXP SC16IS750,
0009 - "nxp,sc16is752" for NXP SC16IS752,
0010 - "nxp,sc16is760" for NXP SC16IS760,
0011 - "nxp,sc16is762" for NXP SC16IS762.
0012 - reg: I2C address of the SC16IS7xx device.
0013 - interrupts: Should contain the UART interrupt
0014 - clocks: Reference to the IC source clock.
0015 OR (when there is no clock provider visible to the platform)
0016 - clock-frequency: The source clock frequency for the IC.
0017
0018 Optional properties:
0019 - gpio-controller: Marks the device node as a GPIO controller.
0020 - #gpio-cells: Should be two. The first cell is the GPIO number and
0021 the second cell is used to specify the GPIO polarity:
0022 0 = active high,
0023 1 = active low.
0024 - irda-mode-ports: An array that lists the indices of the port that
0025 should operate in IrDA mode.
0026
0027 Example:
0028 sc16is750: sc16is750@51 {
0029 compatible = "nxp,sc16is750";
0030 reg = <0x51>;
0031 clocks = <&clk20m>;
0032 interrupt-parent = <&gpio3>;
0033 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
0034 gpio-controller;
0035 #gpio-cells = <2>;
0036 };
0037
0038 * spi as bus
0039
0040 Required properties:
0041 - compatible: Should be one of the following:
0042 - "nxp,sc16is740" for NXP SC16IS740,
0043 - "nxp,sc16is741" for NXP SC16IS741,
0044 - "nxp,sc16is750" for NXP SC16IS750,
0045 - "nxp,sc16is752" for NXP SC16IS752,
0046 - "nxp,sc16is760" for NXP SC16IS760,
0047 - "nxp,sc16is762" for NXP SC16IS762.
0048 - reg: SPI chip select number.
0049 - interrupts: Specifies the interrupt source of the parent interrupt
0050 controller. The format of the interrupt specifier depends on the
0051 parent interrupt controller.
0052 - clocks: phandle to the IC source clock.
0053
0054 Optional properties:
0055 - gpio-controller: Marks the device node as a GPIO controller.
0056 - #gpio-cells: Should be two. The first cell is the GPIO number and
0057 the second cell is used to specify the GPIO polarity:
0058 0 = active high,
0059 1 = active low.
0060 - irda-mode-ports: An array that lists the indices of the port that
0061 should operate in IrDA mode.
0062
0063 Example:
0064 sc16is750: sc16is750@0 {
0065 compatible = "nxp,sc16is750";
0066 reg = <0>;
0067 clocks = <&clk20m>;
0068 interrupt-parent = <&gpio3>;
0069 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
0070 gpio-controller;
0071 #gpio-cells = <2>;
0072 };
