-Device tree configuration for the Mellanox I2C SMBus on BlueField SoCs
-
-Required Properties:
-
-- 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:
-		1) Smbus block registers.
-		2) Cause master registers.
-		3) Cause slave registers.
-		4) Cause coalesce registers (if compatible isn't set
-		   to "mellanox,i2c-mlxbf1").
-
-- 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.
-
-Example:
-
-i2c@2804000 {
-	compatible = "mellanox,i2c-mlxbf1";
-	reg =	<0x02804000 0x800>,
-		<0x02801200 0x020>,
-		<0x02801260 0x020>;
-	interrupts = <57>;
-	clock-frequency = <100000>;
-};
-
-i2c@2808800 {
-	compatible = "mellanox,i2c-mlxbf2";
-	reg =	<0x02808800 0x600>,
-	        <0x02808e00 0x020>,
-		<0x02808e20 0x020>,
-		<0x02808e40 0x010>;
-	interrupts = <57>;
-	clock-frequency = <400000>;
-};
