* **Refactor** * GPIO subsystem moved to a descriptor-based model for per-pin ownership and runtime pin management; many platform drivers now acquire/release descriptors. * Device trees and drivers now use GPIO phandle-style pin specifications across all boards and all drivers. * **Behavior** * Device list now encodes per-device status (ok/disabled); boot will skip disabled devices accordingly. * **Deprecation** * Legacy GPIO HAL marked deprecated and replaced with descriptor-based interfaces. * **Chores** * Bindings and platform configs updated to the new GPIO pin-spec format.
