This patch set hasn't been upstream yet to OpenBMC vanilla and  Its
not specific to openbmc/linux dev-6.6 tree.
We plan to upstream it to Linux version 6.11 (I believe it the next
few weeks), since we need to upgrade the NPCM from dev-6.1 to dev-6.6,
we would appreciate if you could add it now to dev-6.6
