Chip is Bosch Sensortec BME280

Comment 2 by Nikolaus Schaller, Jun 7, 2016

there is one going upstream soon:

https://git.kernel.org/cgit/linux/kernel/git/jic23/iio.git/commit/?h=
testing&id=14beaa8f5ab11b881c5e822e2474f5278d0946d5

We just need to fix DT.

A new feature branch work/hns/sensors/bme280 has been created.

There is a new iio driver for all BMP/BME variants in the works and 
might appear in 4.8:

V2 of that driver has been integrated in our tree:

http://git.goldelico.com/?p=gta04-kernel.git;a=shortlog;h=refs/heads/
work/test/bmp280

It has only one minor issue before we can close this issue: the 
driver can't be compiled as a Module. This has been reported to the 
author.

So let's await it to arrive through linus/master and then fix our 
defconfig.
