Device Driver Enumeration Start Values
Each device driver can extend the existing command IDs, event IDs and
return codes. In order to avoid conflicts, these enumerations must be
unique so that no two device drivers share the same enumeration values.
The macros below define the enumeration start values for each device
driver. Within each device driver's .h file, the enumeration values for
new command IDs, event IDs and return codes should begin with the
appropriate value from the list below. Each driver can add up to 65535
new types before any conflicts occur. Also note that each driver should
prefix all macros, functions, non-static and non-automatic variables with
the prefixes shown below.
(NOTE: all drivers should use the return code of ADI_DEV_RESULT_SUCCESS,
which has the value 0, for all successful function calls.)
For example, the PPI driver uses the prefix "ADI_PPI" and "adi_ppi" and
begins it's enumeration values starting with ADI_PPI_ENUMERATION_START.
When new drivers are added to the distribution, begin the enumeration
for the new driver with the value indicated below, then replace that value
on the line below with it's current value + 0x10000.
Next driver enumeration starts at -> 0x40290000
