To prevent handling glitch signals during MTCMOS on/off
transitions,
SMI requires clamp and reset operations. Parse the reset settings
for
SMI LARBs and the clamp settings for the SMI Sub-Common. Register
genpd callback for the SMI LARBs located in image, camera and IPE
subsystems, and apply reset and clamp operations within the
callback.

You did not respond to previous review. Sending the same while
ignoring
previous review is obvious NAK.
Apologies for missing the message. In the v6 patch, I replaced
'pm_runtime_enable' with 'devm_pm_runtime_enable'. You pointed out that
this change might alter the cleanup order and potentially introduce
errors.

v6:
https://lore.kernel.org/lkml/20250408033206.12176-3-friday.yang@mediatek.com/ (local)

Therefore, in the v7 patch, I reverted this change and continued using
'pm_runtime_enable' in the SMI driver. However, I did not include a
clear description of the changes between v6 and v7 in the cover letter.

v7:
https://lore.kernel.org/lkml/9f01a9a4-89b2-4bfc-97cd-827be989ef16@kernel.org/ (local)

In the v8 patch, I have added a description in the cover letter.
This series just add functions for SMI clamp and not change anything
else. Is this acceptable to you?

Best regards,
Krzysztof
