This set of patches brings support for the Himax HX83100A touch controller. To properly bring the chip up, support for regulator handling is also added. I have no access to datasheets. So, like the original driver code that's being extended here, this code is mostly based on the quite convoluted, GPLv2 licensed manufacturer drivers for Android. I included links to sources and references where appropriate. A number of people tested this patch set on Lenovo ThinkSmart View (CD-18781Y) devices. That device has a variant utilizing a Innolux P080DDD-AB2 LCM. This LCM comes with the HX83100A. I would really appreciate if people using HX83112B chips could give this set a run to ensure nothing broke.
