Subject: [PATCH 0/6] input: himax_hx83112b: add support for HX83100A

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.

Thanks,
Felix
