-         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.
