You can drop this one and add 'minItems: 3' to the first case.

Similar here too with the prior case. Or use 'minItems: 1' in the first 
case. That additional allows the 2 entry case, but why isn't that valid? 
Couldn't a board only support default+state_100mhz?

Okay, I will do that.

Logically not, for board, if support SD3.0 mode, this means it support both SDR104/SDR50/DDR50/HS200/HS400
State_100mhz is used for SDR50 and DDR50, state_200mhz is used for SDR104/HS200/HS400.

So, if there is state_100mhz, there should be state_200mhz.
