You lost mail threading. This makes reading this difficult for us. Plus
you sent something non-applicable (patch #2), so please resend.

Knowing recent Samsung reluctance to extend existing drivers and always
duplicate, please provide description/analysis why this driver cannot be
combined with existing driver. The answer like: we need several syscon
because we do not implement other frameworks (like interconnect) are not
valid.

Best regards,
Krzysztof

Hello, Krzysztof
Thanks for your review.

patch#2 was sent to the wrong format so sent again.
Sorry for causing confusion.

This patch is specialized in Artpec-8,
the SoC Platform of Axis Communication, and is newly applied.
Since the target SoC platform is different from the driver previously
used by Samsung, it is difficult to merge with the existing driver.

Thanks.
