1 * Technologic Systems I2C-FPGA's GPIO controller bindings
4 TS-4900's FPGA encodes the GPIO state on 3 bits, whereas the TS-7970's FPGA
5 uses 2 bits: it doesn't use a dedicated input bit.
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
13 - #gpio-cells: Should be two. The first cell is the pin number.
14 - gpio-controller: Marks the device node as a gpio controller.
17 - ngpios: Number of GPIOs this controller is instantiated with,
24 		compatible = "technologic,ts4900-gpio";
26 		#gpio-cells = <2>;
27 		gpio-controller;
28 		ngpios = <32>;
