   1 * NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
   2 * i2c as bus
   3
   4 Required 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 - interrupt-parent: The phandle for the interrupt controller that
  14   services interrupts for this IC.
  15 - interrupts: Should contain the UART interrupt
  16 - clocks: Reference to the IC source clock.
  17
  18 Optional 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
  25 Example:
  26         sc16is750: sc16is750@51 {
  27                 compatible = "nxp,sc16is750";
  28                 reg = <0x51>;
  29                 clocks = <&clk20m>;
  30                 interrupt-parent = <&gpio3>;
  31                 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
  32                 gpio-controller;
  33                 #gpio-cells = <2>;
  34         };
  35
  36 * spi as bus
  37
  38 Required properties:
  39 - compatible: Should be one of the following:
  40   - "nxp,sc16is740" for NXP SC16IS740,
  41   - "nxp,sc16is741" for NXP SC16IS741,
  42   - "nxp,sc16is750" for NXP SC16IS750,
  43   - "nxp,sc16is752" for NXP SC16IS752,
  44   - "nxp,sc16is760" for NXP SC16IS760,
  45   - "nxp,sc16is762" for NXP SC16IS762.
  46 - reg: SPI chip select number.
  47 - interrupt-parent: The phandle for the interrupt controller that
  48   services interrupts for this IC.
  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
  54 Optional 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
  61 Example:
  62         sc16is750: sc16is750@0 {
  63                 compatible = "nxp,sc16is750";
  64                 reg = <0>;
  65                 clocks = <&clk20m>;
  66                 interrupt-parent = <&gpio3>;
  67                 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
  68                 gpio-controller;
  69                 #gpio-cells = <2>;
  70         };
