Subject[PATCH] ARM: dts: imx7ulp: add crypto support
Date
From: Iuliana Prodan <iuliana.prodan@nxp.com>

Add crypto node in device tree for CAAM support.

Noteworthy is that on 7ulp the interrupt line is shared
between the two job rings.

I've just realized that this patch should be merged through the crypto tree,
else bisectability could be affected due to cryptodev-2.6
commit 385cfc84a5a8 ("crypto: caam - disable some clock checks for iMX7ULP")
( https://patchwork.kernel.org/patch/10970017/ )
which should come first.
