OpenIoT & ELC Europe 2016

One can buy 7" android tablets for aprox 35 usd now, assuming one gets the standard q8 Allwinner based model these are actually supported by the mainline linux kernel now.

These tablets use a standard case + SoC + display, which get paired with a different touchscreen-controller, accelerometer and wifi chip for every other batch.

This talk will outline my experience in making a single devicetree file covering all variants using an in kernel hardware autodetection module which creates and applies devicetree changesets depending on the detected hardware.

This talk will give the audience an idea what is and is not possible wrt dynamic devicetree usage as well as give does and don'ts for people who want to use dynamic devicetree themselves.
