Stefano,
Hmm... I see several pmic's that use their own namespace for init:
grep init include/power/*.h shows a few (power_bat_init,
power_fg_init, power_muic_init, pmic_init_max77693). And if you look
at trats.c or trats2.c boards you will see how they call several of
them. Granted, both of those do also call a generic pmic_init() thats
implemented by pmic_max77686 'or' pmic_max8977. So in the case of
those two boards, they have several pmic's, one that uses the generic
pmic_init() namespace, and 2 others that use their own unique
namespace.
Regards,
Tim
