Title:
backport of driver for I2C on Sunrisepoint PCH
Status in HWE Next:
In Progress
Status in linux package in Ubuntu:
In Progress
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.
