[PATCH v2] crypto: caam/qi2 - lower the algorithm priority

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@xxxxxxx>

Lower the priority to 100, as done for QAT in commit
  8024774190a5 ("crypto: qat - lower priority for skcipher and aead algorithms").

The SEC stays reachable by driver name, and user space can raise its
priority through the crypto_user interface.

v2 lowers the priority to 100, as was done for QAT, and leaves the
choice to user space through crypto_user.
---
Changes in v2:
- Drop both the dpaa2_caam.priority module parameter and the
  fsl,qi2-crypto-priority DT property
- Lower the default priority to 100, user space adjust it with
  crypto_user (Herbert).
- No policy in the device tree (Krzysztof, Eric).
- Link to v1: https://lore.kernel.org/r/20260928-for-upstream-caam-qi2-priority-v1-0-e4a8e5f01dbc@xxxxxxx
