dt-bindings: bus: document the stm32 debug bus

2026-03-25T16:40:22+00:00

Document the stm32 debug bus. The debug bus is responsible for checking the debug sub-system accessibility before probing any related drivers.

dt-bindings: bus: aspeed: Require syscon for AST2600 AHB controller

2025-12-15T15:24:58+00:00

The AST2600's ACRY (eliptic curve and RSA crypto engine) requires access to configuration exposed by the AHB controller. The devicetree already describes the AHB controller node as a syscon, so require this in the binding to satisfy the ACRY relationship.
