History

Grzegorz Swiderski 365e9d63d0 dts: bindings: Update Nordic owned memory bindings This concerns both `nordic,owned-memory` and `nordic,owned-partitions`. Introduce a property named `nordic,access`, which is meant to replace the `owner-id` and `perm-*` properties. It allows for describing how multiple domains should access a single memory region, possibly with different permissions per owner, but without having to create more than one DT node for this purpose. This change is also motivated by updated memory protection requirements on the nRF54H20, which mandate that a given memory region must only be reserved by one domain, even if multiple domains can have access to it. This restriction is now described in the binding itself. Signed-off-by: Grzegorz Swiderski <grzegorz.swiderski@nordicsemi.no>	9 months ago
