dt-bindings: gpio: gpio_oxnas: remove obsolete bindings

Browse Source 
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>;
};
};
