Come with one flag or enum, if needed, covering all your cases like this.

Let me explain, this feature is one of the additional software case
adding on base protocol support. if we dont have more than one usecase
or repurposing this feature, why do we need to add enums ? I see one
flag gpi_mode but it's internal to driver not exposed to user or expose
any usecase/feature.

Below was our earlier context, just wanted to add for clarity.

You keep repeating the same. You won't receive any other answer.

So far i was in context to SEs. I am not sure in qualcomm SOC all cores supporting this feature and if it at all it supports, it may have it's own mechanism then what is followed in SE IP. I was probably thinking on my owned IP core hence i was revolving around.

Hope this dt-binding i can conclude somewhere by seeking answer from other IP core owners within qualcomm.

IP blocks like SE can be shared. Here we are talking about I2C sharing.
In future it can be SPI sharing. But design wise it fits better to add
flag per SE node. Same we shall be adding for SPI too in future.


How flag per SE node is relevant? I did not ask to move the property.


Please let me know your further suggestions.
We do not talk about I2C or SPI here only. We talk about entire SoC.
Since beginning. Find other patch proposals and align with rest of
Qualcomm developers so that you come with only one definition for this
feature/characteristic. Or do you want to say that I am free to NAK all
further properties duplicating this one?

Please confirm that you Qualcomm engineers understand the last statement
and that every block will use se-shared, even if we speak about UFS for
example.
This UFS word atleast makes me understand and gave me clarity that i need to talk to different IP owners within qualcomm and get an agreement for my i2c feature. I am not sure if there exist an usecase the way we are sharing for i2c. Also i don't know how we can make similar description if different cores and functionality are different. If you have heard from any other IP core, please keep some usecases/IP names.

Since This demands internal discussion, so give me time to conclude how the IPs are shared and is it the similar to what i have developed here for I2C. (sorry that so far i was in context to my SE protocols/ IPs only).

Best regards,
Krzysztof
