Thanks for working on this !
For the record, this is the driver for the GXL Family (S905X, S905D, S905W,
S905L, S805X, S805Y) and GXM (S912) only.
The previous GXBB family crypto accelerator seems broken, thus not supported,
And the next G12A/G12B/SM1 (S905X2, S905Y2, S905D2, S922X, A311D, S905X3,
S905Y3, S905D3) generation has a slightly
different crypto accelerator HW, with different supported features, with other
bugs and limitations !

I can see a few (~170) interrupts on the jr0 interrupt then nothing.
Is there a particular issue with hmac-sha256 with the linux CAAM driver ?
When disabling the CAAM hash functions or using another cipher & integrity
pair, it works like a charm.
Thanks,

For the third patch, it may be good to also add the same to the GXL dtsi, no ?
Anyway :
