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.
