[PATCH v7 0/4] i2c-smbus: add support for HOST NOTIFY

[Benjamin Tissoires]

Hi,

this is mostly a resubmission of the v6 with the acks, tested-by and few typos
here and there.

We really need this to be integrated in the kernel to be able to finally
support the touchpads found in many laptops (such as the Lenovo Thinkpad series,
some HPs, and probably many others). Currently those laptops are running the
fallback mechanism over PS/2 which is full of bugs as it has not been given
the same QA than the RMI4 over SMBus (Windows uses RMI4 over SMBus).

RMI4 is now in Linus' tree since v4.6, so it would be nice to see Host Notify
in the I2C tree as well.

Cheers,
Benjamin
