dt-bindings: Remove Netlogic bindings 



Support for Netlogic was removed in commit 95b8a5e0 ("MIPS: Remove
NETLOGIC support"). Remove the now unused bindings.

The GPIO binding also includes "brcm,vulcan-gpio", but it appears to be
unused as well as Broadcom Vulkan became Cavium ThunderX2 which is ACPI
based.

Netlogic XLP Family GPIO

========================



This GPIO driver is used for following Netlogic XLP SoCs:

	XLP832, XLP316, XLP208, XLP980, XLP532

This GPIO driver is also compatible with GPIO controller found on

Broadcom Vulcan ARM64.



Required properties:

-------------------



- compatible: Should be one of the following:

  - "netlogic,xlp832-gpio": For Netlogic XLP832

  - "netlogic,xlp316-gpio": For Netlogic XLP316

  - "netlogic,xlp208-gpio": For Netlogic XLP208

  - "netlogic,xlp980-gpio": For Netlogic XLP980

  - "netlogic,xlp532-gpio": For Netlogic XLP532

  - "brcm,vulcan-gpio": For Broadcom Vulcan ARM64

- reg: Physical base address and length of the controller's registers.

- #gpio-cells: Should be two. The first cell is the pin number and the second

  cell is used to specify optional parameters (currently unused).

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

- nr-gpios: Number of GPIO pins supported by the controller.

- interrupt-cells: Should be two. The first cell is the GPIO Number. The

  second cell is used to specify flags. The following subset of flags is

  supported:

  - trigger type:

	1 = low to high edge triggered.

	2 = high to low edge triggered.

	4 = active high level-sensitive.

	8 = active low level-sensitive.

- interrupts: Interrupt number for this device.

- interrupt-controller: Identifies the node as an interrupt controller.



Example:



	gpio: xlp_gpio@34000 {

		compatible = "netlogic,xlp316-gpio";

		reg = <0 0x34100 0x1000

		       0 0x35100 0x1000>;

		#gpio-cells = <2>;

		gpio-controller;

		nr-gpios = <57>;



		#interrupt-cells = <2>;

		interrupt-parent = <&pic>;

		interrupts = <39>;

		interrupt-controller;

	};

Device tree configuration for the I2C controller on the XLP9xx/5xx SoC



Required properties:

- compatible      : should be "netlogic,xlp980-i2c"

- reg             : bus address start and address range size of device

- interrupts      : interrupt number



Optional properties:

- clock-frequency : frequency of bus clock in Hz

                    Defaults to 100 KHz when the property is not specified



Example:



i2c0: i2c@113100 {

	compatible = "netlogic,xlp980-i2c";

	#address-cells = <1>;

	#size-cells = <0>;

	reg = <0 0x113100 0x100>;

	clock-frequency = <400000>;

	interrupts = <30>;

	interrupt-parent = <&pic>;

SPI Master controller for Netlogic XLP MIPS64 SOCs

==================================================



Currently this SPI controller driver is supported for the following

Netlogic XLP SoCs:

	XLP832, XLP316, XLP208, XLP980, XLP532



Required properties:

- compatible		: Should be "netlogic,xlp832-spi".

- #address-cells	: Number of cells required to define a chip select address

			  on the SPI bus.

- #size-cells		: Should be zero.

- reg			: Should contain register location and length.

- clocks		: Phandle of the spi clock

- interrupts		: Interrupt number used by this controller.



SPI slave nodes must be children of the SPI master node and can contain

properties described in Documentation/devicetree/bindings/spi/spi-bus.txt.



Example:



	spi: xlp_spi@3a100 {

		compatible = "netlogic,xlp832-spi";

		#address-cells = <1>;

		#size-cells = <0>;

		reg = <0 0x3a100 0x100>;

		clocks = <&spi_clk>;

		interrupts = <34>;

		interrupt-parent = <&pic>;



		spi_nor@1 {

			compatible = "spansion,s25sl12801";

			#address-cells = <1>;

			#size-cells = <1>;

			reg = <1>;	/* Chip Select */

			spi-max-frequency = <40000000>;

		};

};
