So the idea is to access the SSC-dedicated GPIO pins with a special instance of the TLMM driver and then enable the sensors normally managed by the sensor hub? This is a GREAT feat, as we don't know if we will ever be able to get any proper Hexagon firmware for the sensor hubs. Yours, Linus Walleij
