- * FILE: drv.c

- * PURPOSE:
- * Conventional device interface for debugging/monitoring of the
- * driver and h/w using unicli. This interface is also being used
- * by the SME linux implementation and the helper apps.

-/*
- * Porting Notes:
- * Part of this file contains an example for how to glue the OS layer
- * with the HIP core lib, the SDIO glue layer, and the SME.
- *
- * When the unifi_sdio.ko modules loads, the linux kernel calls unifi_load().
- * unifi_load() calls uf_sdio_load() which is exported by the SDIO glue
- * layer. uf_sdio_load() registers this driver with the underlying SDIO driver.
- * When a card is detected, the SDIO glue layer calls register_unifi_sdio()
- * to pass the SDIO function context and ask the OS layer to initialise
- * the card. register_unifi_sdio() allocates all the private data of the OS
- * layer and calls uf_run_unifihelper() to start the SME. The SME calls
- * unifi_sys_wifi_on_req() which uses the HIP core lib to initialise the card.
