Introduce support for Broadcom Serial Controller (BSC) I2C bus found in the Kona family of Mobile SoCs. FIFO hardware is utilized but only standard mode (100kHz), fast mode (400kHz), fast mode plus (1MHz), and I2C high-speed (3.4 MHz) bus speeds are supported.

|
|
|
|
BCM11130
|
|
BCM11140
|
|
BCM11351
|
|
BCM28145

|
|
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>
|
