Added I2C SMBus driver and device tree bindings documentation.
This patch set depends on ARCH_MLNX_BLUEFIELD. There is separate
effort that aims to add support for the Mellanox BlueField SoC
to the kernel tree.
Changes since v1:
1) Device bindings documentation:
- Enumerate the device resources.
- Edit the 'compatible' property to make it less generic.
- Remove the 'bus' index property and replace i with a
standard approach to read the bus identifier.
- Get rid of the 'profile' property.
- Use 'clock-frequency' property instead of 'bus-freq'.
- Convert the clock frequency from KHz to Hz.
- Remove useless examples.
2) Device driver source:
- Update the '.compatible' field of of_device_id.
- Update mlx_i2c_of_probe() call to extract the bus id
from the pre-defined aliases.
- Don't check the profile property.
- Read the 'clock-frequency' property to get the timing
parameters.
- Convert the timing configuration from KHz to Hz.
