21 | * Porting Notes: | |
22 | * Part of this file contains an example for how to glue the OS layer | |
23 | * with the HIP core lib, the SDIO glue layer, and the SME. | |
24 | * | |
25 | * When the unifi_sdio.ko modules loads, the linux kernel calls unifi_load(). | |
26 | * unifi_load() calls uf_sdio_load() which is exported by the SDIO glue | |
27 | * layer. uf_sdio_load() registers this driver with the underlying SDIO driver. | |
28 | * When a card is detected, the SDIO glue layer calls register_unifi_sdio() | |
29 | * to pass the SDIO function context and ask the OS layer to initialise | |
30 | * the card. register_unifi_sdio() allocates all the private data of the OS | |
31 | * layer and calls uf_run_unifihelper() to start the SME. The SME calls | |
32 | * unifi_sys_wifi_on_req() which uses the HIP core lib to initialise the card. | |
