[PATCH v11 19/22] wifi: nxpwifi: add core driver implementation

Jeff Chen
2026-04-28T19:42:19Z

Add the core layer of the nxpwifi driver, providing the primary logic and
infrastructure for managing the wireless adapter.

Implement adapter registration, initialization, and teardown; define the
main driver execution paths for TX/RX, command processing, and event
handling; and add firmware download and wakeup support. Introduce power
management integration, workqueue handling, and interrupt processing, and
provide debug and dump facilities for diagnostics.

Define the core data structures and interfaces in main.h, and establish
the nxpwifi_if_ops abstraction for use by bus-specific drivers.
