From: Karel Balej <balejk@xxxxxxxxx> This patch series generalizes the Imagis touchscreen driver to support other Imagis chips, namely IST3038B, which use a slightly different protocol. 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]. In particular, the driver for the regulator needed by the touchscreen on this device has not been rewritten for mainline yet. Note that this is a prerequisite for this patch [2] which implements support for touch keys for Imagis touchscreens that have it.
