Subject: [PATCH v2 0/5] input/touchscreen: imagis: add support for IST3032C

From: Karel Balej <karelb@...li.ms.mff.cuni.cz>

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.

Changes in v2:
- Do not rename the driver.
- Do not hardcode voltage required by the IST3032C.
- Use Markuss' series which generalizes the driver.
- Separate bindings into separate patch.
- v1: https://lore.kernel.org/all/20230926173531.18715-1-balejk@matfyz.cz/
