Subject: [PATCH v9 18/23] dt-bindings: crypto: meson: support new SoC's
Now crypto module available at G12A/G12B/S4/A1/SM1/AXG.
1. Add new compatibles:
- amlogic,g12a-crypto
- amlogic,axg-crypto
- amlogic,a1-crypto
- amlogic,s4-crypto (uses a1-crypto as fallback)
Difference between this compatibles:
* Different registers offset and the number of setup descriptors.
* GXL doesn't support hashing like the others.
* G12A/B and A1/S4 crypto HW don't support 192 AES key.
* GXL, G12A/B and AXG require a reverse IV key before processing.
2. Add power-domains in schema, which is required only for A1.
This is specific vendor design: in old SoC's power domain for
crypto HW was not configurable, but in A1-series it is configurable.
