+
+- compatible : should be "mellanox,i2c-mlxbf1" or "mellanox,i2c-mlxbf2".
+
+- reg : address offset and length of the device registers. The
+ registers consist of the following set of resources:

+ 2) Cause master registers.
+ 3) Cause slave registers.
+ 4) Cause coalesce registers (if compatible isn't set

+
+- interrupts : interrupt number.
+
+Optional Properties:
+
+- clock-frequency : bus frequency used to configure timing registers;
+ allowed values are 100000, 400000 and 1000000;
+ those are expressed in Hz. Default is 100000.
