For the whole series:

Reviewed-by: Nícolas F. R. A. Prado <nfraprado@...labora.com>

And also

Tested-by: Nícolas F. R. A. Prado <nfraprado@...labora.com>

on mt8192-asurada-spherion. PCIe resets work as intended by adding on the pcie
node 

+                       resets = <&infracfg MT8192_INFRA_RST2_PEXTP_PHY_SWRST>,
+                                <&infracfg MT8192_INFRA_RST4_PCIE_TOP_SWRST>;
+                       reset-names = "phy", "mac";

Thanks for the great work on this series, Rex!
