Hi Ferruh,
As Javier mentioned, there is already a framework for the Cypress
devices in the kernel. Please make sure your patches build on what is
already there. Until then, I have nothing further to add.
Thanks,

Hi Henrik,
Thank you for your response.
We now understand the requirement for our driver and we will submit a
new patchset as soon as possible.
Best Regards,

Hello Henrik,
After Javier's and your comment, we started an effort to update driver
and re-structured it similar to the existing Gen3 driver. We are close
to submit a patch-set for updated code, but this effort showed that this
new patch-set also won't be an incremental commit to existing driver but
will have to introduce new files.
Existing driver in the kernel is for Cypress Gen3 devices and it is not
a framework to cover Gen4 devices, Gen4 devices has different host
interface.
This re-structure made driver simpler with cost of removing some
features like ttsp bus or merging modular layers that work with
subscription mechanism into one file with direct function calls.
The concern here for our side is, the next generation touchscreen
controllers may cause similar problem with this Gen3 structure while
adding support to Linux kernel for them.
Before finalizing the work, we want to learn if introducing new files
for new driver is acceptable and our effort is inline with your request,
can you please comment on it?
Thanks and Regards,
ferruh
