What I want to say is there are only 4 possible values which can be
set for initial_mode and suspend_state modes:

#define REGULATOR_MODE_FAST                     0x1
#define REGULATOR_MODE_NORMAL                   0x2
#define REGULATOR_MODE_IDLE                     0x4
#define REGULATOR_MODE_STANDBY                  0x8

these are defined in include/linux/regulator/consumer.h (core regulator file).
'of_map_modes' of each regulator driver ultimately set these values only.
I want to suggest that these values can directly be pass from dts.
Different dts can pass different values according to the regulator
they are using,
no need to decode them from of_map_modes function.
Let me know your comments on this.

Saurabh
