You don't need the '-1' because the unit-address makes the node name unique. Node names are supposed to be generic based on the class/type of device.

Indeed, U-boot relies on the "crypto" alias. This is true for all SoCs with CAAM crypto engine, a pretty lengthy list. Could you please clarify? Also: Is numbering needed even when there is a single instance of the block? Looking at a recent discussion https://lore.kernel.org/patchwork/patch/991718 I see the proposal is for the ID to be optional: > Alias names are often suffixed with a numeric ID, especially when there may > be multiple instances of the same type. The ID typically corresponds to the [...] Thanks, Horia
