  1. * NXP SC16IS7xx advanced Universal Asynchronous Receiver-Transmitter (UART)
    2. 

  2. * i2c as bus
    3. 

  3. 

  4. Required properties:
    5. 

  5. - compatible: Should be one of the following:
    6. 

  6.   - "nxp,sc16is740" for NXP SC16IS740,
    7. 

  7.   - "nxp,sc16is741" for NXP SC16IS741,
    8. 

  8.   - "nxp,sc16is750" for NXP SC16IS750,
    9. 

  9.   - "nxp,sc16is752" for NXP SC16IS752,
    10. 

  10.   - "nxp,sc16is760" for NXP SC16IS760,
    11. 

  11.   - "nxp,sc16is762" for NXP SC16IS762.
    12. 

  12. - reg: I2C address of the SC16IS7xx device.
    13. 

  13. - interrupts: Should contain the UART interrupt
    14. 

  14. - clocks: Reference to the IC source clock.
    15. 

  15. 

  16. Optional properties:
    17. 

  17. - gpio-controller: Marks the device node as a GPIO controller.
    18. 

  18. - #gpio-cells: Should be two. The first cell is the GPIO number and
    19. 

  19.   the second cell is used to specify the GPIO polarity:
    20. 

  20.     0 = active high,
    21. 

  21.     1 = active low.
    22. 

  22. 

  23. Example:
    24. 

  24.         sc16is750: sc16is750@51 {
    25. 

  25.                 compatible = "nxp,sc16is750";
    26. 

  26.                 reg = <0x51>;
    27. 

  27.                 clocks = <&clk20m>;
    28. 

  28.                 interrupt-parent = <&gpio3>;
    29. 

  29.                 interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
    30. 

  30.                 gpio-controller;
    31. 

  31.                 #gpio-cells = <2>;
    32. 

  32.         };
    33. 

  33. 

  34. * spi as bus
    35. 

  35. 

  36. Required properties:
    37. 

  37. - compatible: Should be one of the following:
    38. 

  38.   - "nxp,sc16is740" for NXP SC16IS740,
    39. 

  39.   - "nxp,sc16is741" for NXP SC16IS741,
    40. 

  40.   - "nxp,sc16is750" for NXP SC16IS750,
    41. 

  41.   - "nxp,sc16is752" for NXP SC16IS752,
    42. 

  42.   - "nxp,sc16is760" for NXP SC16IS760,
    43. 

  43.   - "nxp,sc16is762" for NXP SC16IS762.
    44. 

  44. - reg: SPI chip select number.
    45. 

  45. - interrupts: Specifies the interrupt source of the parent interrupt
    46. 

  46.   controller. The format of the interrupt specifier depends on the
    47. 

  47.   parent interrupt controller.
    48. 

  48. - clocks: phandle to the IC source clock.
    49.

  50. Optional properties:
    51. 

  51. - gpio-controller: Marks the device node as a GPIO controller.
    52. 

  52. - #gpio-cells: Should be two. The first cell is the GPIO number and
    53. 

  53.   the second cell is used to specify the GPIO polarity:
    54. 

  54.     0 = active high,
    55. 

  55.     1 = active low.
    56. 

  56. 

  57. Example:
    58.
