-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>;
-};
