[PATCH v4] ARM: dts: at91: sama7g5: Add crypto nodes

From: Tudor Ambarus
Date: Tue Feb 08 2022 - 06:32:07 EST


Describe and enable the AES, SHA and TDES crypto IPs. Tested with the
extra run-time self tests of the registered crypto algorithms.

v4: use the generic "crypto" node name for all the crypto nodes,
as recommended by the DT specification. Add Claudiu's R-b tag.

v3: remove explicit status = "okay", as it's already the default case
when not specified at all.

v2:
- add label to the tdes node
- update commit description and specify testing method
- put clocks and clock-names properties before dmas and dma-names
because the clocks are mandatory, while DMA is optional for TDES and SHA
