Seems that from this series:
https://lore.kernel.org/linux-crypto/20200225161201.1975-5-git@andred.net/T/
only DT patches (2,3,4) were applied.

Would it be ok to go via crypto tree with:
[PATCH v2 1/6] dt-bindings: crypto: fsl-sec4: add snvs clock to pwrkey

and via input tree with:
[PATCH v2 5/6] Input: snvs_pwrkey - enable snvs clock as needed
[PATCH v2 6/6] Input: snvs_pwrkey - only IRQ_HANDLED for our own events
?

Thanks,
Horia
