i2c: bcm-kona: Introduce Broadcom I2C Driver

Broadcom Kona Family I2C

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

This I2C controller is used in the following Broadcom SoCs:

  BCM11130

  BCM11140

  BCM11351

  BCM28145

  BCM28155

Required Properties

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

- compatible: "brcm,bcm11351-i2c", "brcm,kona-i2c"

- reg: Physical base address and length of controller registers

- interrupts: The interrupt number used by the controller

- clocks: clock specifier for the kona i2c external clock

- clock-frequency: The I2C bus frequency in Hz

- #address-cells: Should be <1>

- #size-cells: Should be <0>

Refer to clocks/clock-bindings.txt for generic clock consumer

properties.

Example:

i2c@3e016000 {

	compatible = "brcm,bcm11351-i2c","brcm,kona-i2c";

	reg = <0x3e016000 0x80>;

	interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>;

	clocks = <&bsc1_clk>;

	clock-frequency = <400000>;

	#address-cells = <1>;

	#size-cells = <0>;

};

	  This support is also available as a module.  If so, the module

	  will be called i2c-bcm2835.

config I2C_BCM_KONA

	tristate "BCM Kona I2C adapter"

	depends on ARCH_BCM_MOBILE

	default y

	help

	  If you say yes to this option, support will be included for the

	  I2C interface on the Broadcom Kona family of processors.

	  If you do not need KONA I2C inteface, say N.

config I2C_BLACKFIN_TWI

	tristate "Blackfin TWI I2C support"

	depends on BLACKFIN
