[PATCH 0/4] crypto: caam - add Job Ring support for DPAA2 parts

[Horia Geantă]

This patch set adds support for CAAM's legacy Job Ring backend / interface
on platforms having DPAA2 (Datapath Acceleration Architecture v2), like
LS1088A or LS2088A.

I would like to get the DT patches through the crypto list (to make sure
they don't end up merged before driver support).

Thanks,
Horia

[PATCH 1/4] crypto: caam/jr - add support for DPAA2 parts

[Horia Geantă]

Add support for using the caam/jr backend on DPAA2-based SoCs.
These have some particularities we have to account for:
-HW S/G format is different
-Management Complex (MC) firmware initializes / manages (partially)
the CAAM block: MCFGR, QI enablement in QICTL, RNG

[PATCH 2/4] arm64: dts: freescale: ls208xa: share aliases node

[Horia Geantă]

aliases node is identical for all boards, thus move it
to the common file ls208xa.dtsi.

Unless it's really urgent (usually critical bug fix), the DTS patches
should go through arm-soc tree.  We usually take DTS patches after the
driver counterpart has been accepted by subsystem maintainers, or in the
best case, has landed on mainline.

Thanks for the clarification.

Do I have to re-post the DTS patches once the driver is accepted or a
ping should suffice or...?

Shawn,

Driver support (patch 1/4) has just been applied to the cryptodev-2.6 tree:
297b9cebd2fc crypto: caam/jr - add support for DPAA2 parts

Could you please pick up the DTS patches (2-4/4) in this series?

Thanks,
Horia
