Subject: [PATCH 0/1] Input: Add TouchNetix aXiom touchscreen driver

A Summary of the added features:
 - Add input driver support for TouchNetix aXiom touchscreen controller 
using either I2C or SPI.
 - Support ABS_MT touch reports in axiom_process_u41_report().
 - Support both polling and interrupt mode (trigger low).
 - Add basic documentation and provide example device tree bindings.
 - Provide the basic structure to add firmware and config download in
the future via both I2C and SPI.

I understand the process is already under way to add a driver to support 
aXiom by Marco at Pengutronix.
I think it would be most useful for us to attempt to combine this patch
in order to support both his changes for config/firmware download and 
the patch here for SPI support along with I2C. I would be happy to help 
with this process.
This would allow TouchNetix to support a broader range of users of the
aXiom device family.

I also have a device tree binding however I have not added it sincec
from my understanding this should go in a different patch:
Documentation/devicetree/bindings/input/touchscreen/tnx,axiom.yaml
 
My apologies if there are any obvious mistakes in this patch, this is the
first patch that I have submitted.

Many thanks for your time,
Andrew Thomas
