@Description FM API functions, definitions and enums
The FM module is the main driver module and is a mandatory module
for FM driver users. Before any further module initialization,
this module must be initialized.
The FM is a "single-tone" module. It is responsible of the common
HW modules: FPM, DMA, common QMI, common BMI initializations and
run-time control routines. This module must be initialized always
when working with any of the FM modules.
NOTE - We assumes that the FML will be initialize only by core No. 0!

@Group lnx_ioctl_FM_runtime_control_grp FM Runtime Control Unit
@Description FM Runtime control unit API functions, definitions and enums.
The FM driver provides a set of control routines for each module.
These routines may only be called after the module was fully
initialized (both configuration and initialization routines were
called). They are typically used to get information from hardware
(status, counters/statistics, revision etc.), to modify a current
state or to force/enable a required action. Run-time control may
be called whenever necessary and as many times as needed.
