Browse source

This patch introduce addition wrapper for fixed point 16.16 operations.
Which will be used by later patches to avoid direct member variables
access of fixed_16_16_t structure.

add_fixed16 : takes 2 fixed_16_16_t variable & returns fixed_16_16_t
add_fixed16_u32 : takes fixed_16_16_t & u32 variable & returns fixed_16_16_t
