dt-bindings: gpio: gpio_oxnas: remove obsolete bindings 



Due to lack of maintenance and stall of development for a few years now,
and since no new features will ever be added upstream, remove the
OX810 and OX820 gpio bindings.

* Oxford Semiconductor OXNAS SoC GPIO Controller



Please refer to gpio.txt for generic information regarding GPIO bindings.



Required properties:

 - compatible: "oxsemi,ox810se-gpio" or "oxsemi,ox820-gpio"

 - reg: Base address and length for the device.

 - interrupts: The port interrupt shared by all pins.

 - gpio-controller: Marks the port as GPIO controller.

 - #gpio-cells: Two. The first cell is the pin number and

   the second cell is used to specify the gpio polarity as defined in

   defined in <dt-bindings/gpio/gpio.h>:

      0 = GPIO_ACTIVE_HIGH

      1 = GPIO_ACTIVE_LOW

 - interrupt-controller: Marks the device node as an interrupt controller.

 - #interrupt-cells: Two. The first cell is the GPIO number and second cell

   is used to specify the trigger type as defined in

   <dt-bindings/interrupt-controller/irq.h>:

      IRQ_TYPE_EDGE_RISING

      IRQ_TYPE_EDGE_FALLING

      IRQ_TYPE_EDGE_BOTH

 - gpio-ranges: Interaction with the PINCTRL subsystem, it also specifies the

   gpio base and count, should be in the format of numeric-gpio-range as

   specified in the gpio.txt file.



Example:



gpio0: gpio@0 {

	compatible = "oxsemi,ox810se-gpio";

	reg = <0x000000 0x100000>;

	interrupts = <21>;

	#gpio-cells = <2>;

	gpio-controller;

	interrupt-controller;

	#interrupt-cells = <2>;

	gpio-ranges = <&pinctrl 0 0 32>;

};



keys {

	...



	button-esc {

		label = "ESC";

		linux,code = <1>;

		gpios = <&gpio0 12 0>;

	};

};
