[PATCH v4 0/2] i2c: added driver for Mellanox BlueField SoC

[PATCH v4 0/2] i2c: added driver for Mellanox BlueField SoC

[Khalil Blaiech]

Added I2C SMBus driver and device tree bindings documentation.

Changes since v3:

Device bindings documentation:

   - Re-order property descriptions.
   - Remove useless register addresses from the resource
     description.
   - Mention default clock-frequency value.
   - Fix format issues; remove spaces.
   - Omit "aliases" from Example section.
   - Rename device instance node in Example section.

+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.
+
+- 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>;
+};
