TPS61258: marking decode for YMS

Part Number: TPS61258

Dear TI Expert,

My customer check  the marking of  1pcs TPS61258 sample, and found the YMS is "221". Could you help to advise how to decode it? "22" means which year and month? And "1" means which assembly factory? How does the rule work? Thanks a lot.
