Subhendu Sekhar Behera 2bbd681ba2 i2c: xlp9xx: Driver for Netlogic XLP9XX/5XX I2C controller
Add an I2C bus driver i2c-xlp9xx.c to support the I2C block in the
XLP9xx/XLP5xx MIPS SoC. Update Kconfig and Makefile to add the
CONFIG_I2C_XLP9XX option.

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>;
};
