  The LLCC block in SM8450, SM8550 and SM8650 have a new register
space for Broadcast_AND region. This is used to check that all
channels have bit set to "1", mainly in SCID activation/deactivation.

Previously we were mapping only the Broadcast_OR region assuming
there was only one broadcast register region. Now we also map
Broadcast_AND region.

Why did you ignore the tags? Qualcomm upstreaming guide covers this
case, so please read it before sending patches.

Best regards,
Krzysztof

I was asked to remove the Reviewed-by tag as the previous version of the
patch gave errors on running 'make DT_CHECKER_FLAGS=-m dt_binding_check',
that's why I dropped it.
It was sometime ago, https://lore.kernel.org/all/d78b4bce-7bcd-4ab0-a76b-135cee3ec9b0@linaro.org/

And where is it explained/mentioned? Every tag drop should be documented.

Best regards,

I understand, thanks for pointing out. I will record such tag drops in the change log.
