 * Plat Layer defines the interfaces that the BSP specific file should override
 * The default implementation of the interfaces are present in dhd_linux_platdev.c
 * The data structure/handle to be passed by the DHD to BSP specific file is opaque
 * called plat_info. The data structure is to be maintained purely inside the
 * BSP specific file and hence its kept opaque.
 *
 * There are two types of interface functions
 * 1) Functions that need the interface structure plat_info to be passed down
 *    from DHD.
 * 2) Functions that queries for certain information in BSP specific way and just
 *    returns to DHD - These functions does not take the plat_info as argument.
 *
 * The declarations are grouped accordingly. While adding a new interface function
 * declaration based on the group it belongs to add it in the appropriate section
