Initialize the control handler by reading the platform specific firmware capabilities. Capabilities are features, which are supported by a specific platform (SOC). Each capability is defined with a min, max, range and default value and a corresponding HFI. Implement s_ctrl and g_volatile_ctrl ctrl ops.

2025-02-07media: iris: introduce iris core state management with shared queuesDikshita Agarwal
Introduce a core state management for iris driver with the necessary queues needed for the host firmware communication. There are 3 types of queues: Command queue - driver to write any command to firmware. Message queue - firmware to send any response to the driver. Debug queue - for the firmware to write debug messages. Initialize and configure the shared queues during probe. Different states for core: IRIS_CORE_DEINIT - default state. IRIS_CORE_INIT - core state with core initialized. FW loaded and HW brought out of reset, shared queues established between host driver and firmware. IRIS_CORE_ERROR - error state. ----------- | V ----------- | DEINIT | ----------- ^ / \ / \ / \ / \ v v ----------- ----------. | INIT |-->| ERROR | ----------- ----------.
