RE: [PATCH] Input: Add new driver into Input Subsystem for Synaptics DS4 touchscreen I2C devices

Hi Dmitry/Henrik,

Given that the other group at Synaptics works on general version of RMI4
driver what is the benefit of having separate driver for DS4 line? I can
understand keeping one copy of older driver in staging so that some
customers coudl still use hardware while universal implementation is
being developed, but I do not see why we would want to have 3 separate
drivers.

Thank you for your suggestions and comments!

We agree with your opinion. We will submit the driver as a patch on top 
of STE's driver since it is in the staging.

And we would like to state our purpose clearly why we are doing this 
including the following:
- We have customers that require a Touch Controller platform specific
 driver, that is protocol specific, following a single source file structure.
- There is also a requirement that the platform specific driver has to be 
 adopted and included into the Linux kernel.

As you are aware, Chris' team is working on general version of RMI4. 
However customers still require a platform specific driver for Touch 
Controller platform. We really hope both drivers (general RMI4 driver 
and STE's driver) being adopted into the kernel. This will allow us to 
provide the best flexibility possible to customers.

Your opinion will be greatly appreciated.
