Bug description:
  Some newly released laptops talk to touchpad via I2C to provide
  advanced functions. The new Intel Skylake uses Sunrisepoint PCH, thus
  the I2C on it needs to to enabled in order to support these touchpads.

  Intel is still working on the driver. There are six versions so far:
  v1: https://lkml.org/lkml/2015/3/31/255
  v2: https://lkml.org/lkml/2015/5/25/298
  v3: https://lkml.org/lkml/2015/6/1/429
  v4: https://lkml.org/lkml/2015/6/15/160
  v5: https://lkml.org/lkml/2015/7/6/317
  v6: https://lkml.org/lkml/2015/7/27/599

  The driver supports SPI, UART, and I2C on the Sunrisepoint PCH, but
  we'll only focus on the I2C part.
