It also adds necessary information to the driver so that the IST3032C touchscreen can be used with it. The motivation for this 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 this patch [3] which implements support for touch keys for Imagis touchscreens that have it.
