-	  Add support for the Amlogic Meson I2C driver.
+	  Add support for the I2C controller available in Amlogic Meson
+	  SoCs. The controller supports programmable bus speed including
+	  standard (100kbits/s) and fast (400kbit/s) speed and allows the
+	  software to define a flexible format of the bit streams. It has an
+	  internal buffer holding up to 8 bytes for transfers and supports
+	  both 7-bit and 10-bit addresses.
