The far future goal is to arrive at a completely open implementation, but nobody knows how to get there. Therefore we bake smaller bread :) step 1: get SoC integration right and stable (this is what this series is for) step 2: make the open source kernel driver work with closed-source libs step 3: write open-source replacements for user-space > >> The kernel modules built from this project have successfully >> demonstrated to work with the DTS definitions from this patch set on >> AM335x BeagleBone Black, DM3730 and OMAP5 Pyra and Droid 4.

Phillip has testes something on a83. BR and thanks, Nikolaus
