Subject: [PATCH] arm: sun7i: cubietruck: Enable the i2c controllers
|
|
|
|
The Cubietruck makes use of the first three i2c controllers found on the
|
|
Allwinner A20; i2c-0 is used internally for the PMIC, i2c-1 is exposed on
|
|
the board headers, and i2c-2 is used for DDC on the VGA connector. This
|
|
patch enables them in the device tree.
