I2C trackpad

[Ian FREISLICH]

Hey,

I recently acquired a new laptop (Asus UX490U) which for the most part
works with current except that:

1. Sound output doesn't work.
2. The trackpad doesn't work.

I'm not bothered about sound and I haven't investigated that yet.  The
trackpad not working is a nuisance, but I don't think that there's a
short term fix.  I think it's connected via an I2C bus on one of two I2C
controllers that don't have a driver attached:

none2 at pci0:0:21:0:      class=0x118000 card=0x1c301043 chip=0x9d608086
rev=0x21 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Sunrise Point-LP Serial IO I2C Controller'
    class      = dasp
none3 at pci0:0:21:1:      class=0x118000 card=0x1c301043 chip=0x9d618086
rev=0x21 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Sunrise Point-LP Serial IO I2C Controller'
    class      = dasp

I've done some research and it looks like support is a long way off but
I'm hoping someone has a work in progress I can test or hack on.

Ian
