the description is good now. It would be nice if this could also be
mentioned in the Reference Manual.

Please replace "add" with "fix" in the subject, as I requested earlier:
"reset: imx7: Fix i.MX8MP PCIe PHY PERST support".

And add a fixes line:

Fixes: e08672c03981 ("reset: imx7: Add support for i.MX8MP SoC")

With those two changes,
