From: Chris Spencer <christopher.spencer@xxxxxxxxx>
This patch series adds support for the i.MX8MQ to the CAAM driver. This
is mostly adapted from corresponding changes in the NXP repo. The
patches are based on v5.0-rc7.
RFC for now because I do not have any other boards to test it on.
Hopefully people can verify this change on other boards. The only thing
that I think is potentially problematic is that the RNG is now
initialised via the job ring instead of interfacing directly with the
DECO.
In principle, support for the i.MX8MM can be added by just checking for
fsl,imx8mm everywhere we are checking for fsl,imx8mq. I left this out
because there is currently no upstream support for the i.MX8MM, and I
wouldn't be able to test it anyway.
The i.MX8QM and i.MX8QXP will take more work to support because the
driver needs to be updated to handle the SECO.
I have copied the DT nodes for imx8mq.dtsi below. I will submit these
separately to the imx tree if/when these changes are accepted.

Chris Spencer (4):
crypto: caam - fix detection of i.MX8 SoC
crypto: caam - do not initialise clocks on the i.MX8
crypto: caam - correct DMA address size for the i.MX8
crypto: caam - use job ring for RNG instantiation instead of DECO
