+/*
+ * 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.
