Hello,

this patch series generalizes the Imagis touchscreen driver to support
other Imagis chips, namely IST3038B and IST3032C, which use a slightly
different protocol.

The motivation for IST3032C is the samsung,coreprimevelte smartphone
with which this series has been tested. However, the support for this
device is not yet in-tree, the effort is happening at [1]. Preliminary
version of the regulator driver needed to use the touchscreen on this
phone can be found here [2].

Note that this is a prerequisite for (at least a part of) this series
[3] which among other things implements support for touch keys for
Imagis touchscreens that have it.
