All sensors are now functional on N9:

• apds990x (ALS/PS = combined ambient light / proximity)
• lis302 (accelerometer)
• ak8975 (magnetometer)

Sadly only lis302 is the same on both N9 and N950 (positioned a bit differently). N950 uses bh1770glc/sfh7770 for ALS/PS (supported in kernel), but magnetometer ak8974 is tricky one (no support for it mainline).

In Mer/Nemo, ALS/PS and accelerometer work by adding appropriate config file to sensorfw package, but ak8975 needs additional coding (since driver in mainline is quite different than the old one). I have that code ready, but I'm unsure how to properly test it so I'll try to get some info about that during next week.

I'll move onto audio bits after sensorfw is done (since we have 3 audio chips this could be rather complicated).There are still important things left to be done (apart from missing bits for N950) like CMT and BME, so I hope someone might take a shot at those.

On the following link are current kernel patches: https://www.dropbox.com/s/ogx2nbzoxf...x.tar.bz2?dl=1 Consider them to be tentative (not final in any way, shape, form or fashion) and that file will simply be overwritten with fresh patches from time to time.
