These are bound into struct cc33xx_if_operations and accessed via io.h in order to abstract multiple transport interfaces such as SPI in the future. The CC33xx driver supports the SDIO in-band IRQ option so the IRQ from the device received here as well. Unlike wl1xxx products, there is no longer mapping between HW and SDIO / SPI address space of any kind. There are only 3 valid addresses for control, data and status transactions each with a predefined structure.

Similar to wlcore, all commands eventually reach __cc33xx_cmd_send which fills a generic command header and send the buffer via the IO abstraction layer. Unlike wlcore, there is no polling for command completion which is received via an interrupt which signals cc->command_complete.

The FW comes in 2 parts - a 2nd stage bootloader (cc33xx_2nd_loader.bin) and the actual FW (cc33xx_fw.bin). Each file is requested from user space, and transferred to device chunk by chunk. A dedicated IRQ is excepted after each stage (Device power-on -> 2nd stage loader -> FW). This logic is implemnted in cc33xx_init_fw.

Notably: cc33xx_irq - Handles IRQs received from the device. process_core_status - Core status is a new concept in CC33xx. it's a structure that is appended to each transfer from the device and contains its most up-to-date status report (IRQs, buffers, etc.). See struct core_status for details. process_event_and_cmd_result - Responses to driver commands and FW events both arrive asynchronously. Therefore, driver cannot know what he read from HW until inspecting the payload. This code reads and dispatches the data accordingly. cc33xx_recovery_work - Driver supports basic recovery on FW crash and other illegal conditions. This implements the recovery flow (Remove all vifs, turn device off and on, download FW, let ieee80211_restart_hw do the rest). irq_deferred_work - Does irq-related work that requires holding the cc->mutex. Thisd is mostly in response to HW's Tx/Rx IRQs. cc33xx_nvs_cb - Callback for the NVS FW request API. Similar to wlcore, this is where the init of the HW is performed. cc33xx_load_ini_bin_file - Loads a configuration file from user-space via the request FW API. The structure is described in a separate patch. cc33xx_op_X - MAC80211 operation handlers.

Rx handling starts at cc33xx_rx. Full SKBs are stored at cc->deferred_rx_queue from where they are handed to MAC80211 by calling cc->netstack_work (cc33xx_netstack_work @ main.c). This allows calling ieee80211_rx_ni while new data is being read from HW.

Both trigger cc->tx_work (cc33xx_tx_work @ tx.c) which will call cc33xx_tx_work_locked where data from MAC80211 SKBs will be packed and transferred to HW. An interrupt will then be received from HW indicating that a given frame was transmitted or expired so that its SKB can be freed (cc33xx_tx_immediate_complete).

Scan starts via cc33xx_op_hw_scan (main.c) which calls cc33xx_scan. Scan channels are packed and sent to HW where scanning is managed by FW concurrently to other roles without driver intervention. Scan results are handled like normal management frames and are sent to MAC80211. HW notifies driver of scan completion via dedicated event which triggers a call to cc33xx_scan_completed.
