Subject: [RESEND PATCH v5 0/5] input/touchscreen: imagis: add support for IST3032C

From: Karel Balej <balejk@...fyz.cz>

Hello,

this patch series generalizes the Imagis touchscreen driver to support
other Imagis chips, namely IST3038B and IST3032C.

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.
