Acer C720 has touchpad and light sensor connected to a separate I2C buses. Since the designware I2C host controller driver has two instances on this particular machine we need a way to match the correct instance. Add support for this and then register both C720 touchpad and light sensor. This code is based on following patch from Benson Leung: https://patchwork.kernel.org/patch/3074411/ Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Tested-by: Kirill A.
