dt-bindings: Remove Netlogic bindings

Browse Source 
Support for Netlogic was removed in commit 95b8a5e011 ("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>;
};
};
