Silicon revison on chip marking / rev[B,C,D] in header file?

Hello,

My MPU-6050 has a marking D1X517-C2 on the second line. Should I understand that it's revision C2? In other words, the last two letters of the second line of the marking is the revision. Correct? The datasheet doesn't explicit say it.

Can you also confirm that hardware revision B*, C*, D* should all use CONFIG_MPU_SENSORS_MPU6050B1.

Thanks in advance,

Grégoire

PS: I bought an evaluation board and it has a revision C2 chip produced in 1207 (7th week of 2012) and I have seen some posts last year with some MPU-6050 revision D question. Strange...
