No. The kenrel doc is for the Goldelico kernels which were 2.6.32 some years ago and now reflect the drivers of 3.12 (ff). QtMoko AFAIK uses a 3.7 kernel and since the /sys node names are not stable (and never will be) you might have to do a little guesswork and look into the 3.7 kernel source code to find out how the driver works. Hope this helps, Nikolaus
