pushing your choice even though to reviewers gave you their opinion.
In such case:
No, NAK, for the reasons stated above.
Best regards,
Krzysztof

Sure, taken the notes from both of you.
Shall we wait for the shifting of DTSI file from sc8775p to qcs9100 ?
OR is there any other way to move ahead ?
Please suggest, we shall do whatever guidance from you both.

Do not add code which we already know that it is incorrect or
incomplete. Instead align with your colleagues about proper upstreaming
of this platform.
I am not going to sign off such patches.
Best regards,
Krzysztof

After considering the feedback provided on the subject, We have decided
to keep current SA8775p compatible and ABI compatibility in drivers.
Therefore, this patch is still needed, please continue to review this
patch.
Thank you for your input.
