Well the whole "faith is enough to save you" is an element somewhat present in hinduism. Most hindu scholars believer we're currently going through the Kali Yuga, which is the worst among the 4 cycles the world goes through, in which man is the farthest from god as possible and there is much sin and conflict, altough it is said that, during the Kali Yuga, all you need to do to be eligible for transition into a higher realm is believing and reciting the name of god in prayer, because thats the best thing that is expected from a person during the kali yuga :v
And faith being enough to save you is mostly a new testament thing, IIRC, due to Jesus' sacrifice, but ye, I dont remember many religions having faith as the only actual requirement for salvation, altough there are "more forgiving" beliefs in which even faith isn't a requirement.
In hermeticism, for example, it is said that humanity will eventualy achieve true freedom (freedom from materiality/the body/etc), but seeking knowledge and distancing yourself from the wants of the body and material things speeds up the process quite a bit, and having faith does help (in hermeticism, one of the biggest sins is ignorance from god). Even spiritism, which is derivated from christianity, says that faith isn't a requirement, but having faith while also being a good person and helping others hastens your soul's development, etc.
You'd be hard pressed to find any religions with completely original elements anyway.
