gpio-ts4900.txt (894B)

      1* Technologic Systems I2C-FPGA's GPIO controller bindings
      2
      3This bindings describes the GPIO controller for Technologic's FPGA core.
      4TS-4900's FPGA encodes the GPIO state on 3 bits, whereas the TS-7970's FPGA
      5uses 2 bits: it doesn't use a dedicated input bit.
      6
      7Required properties:
      8- compatible: Should be one of the following
      9		"technologic,ts4900-gpio"
     10		"technologic,ts7970-gpio"
     11- reg: Physical base address of the controller and length
     12       of memory mapped region.
     13- #gpio-cells: Should be two. The first cell is the pin number.
     14- gpio-controller: Marks the device node as a gpio controller.
     15
     16Optional property:
     17- ngpios: Number of GPIOs this controller is instantiated with,
     18  the default is 32. See gpio.txt for more details.

     20Example:
     21
     22&i2c2 {
     23	gpio8: gpio@28 {
     24		compatible = "technologic,ts4900-gpio";
     25		reg = <0x28>;
     26		#gpio-cells = <2>;
     27		gpio-controller;
     28		ngpios = <32>;
     29	};
     30};
