Sorry. Stupid outlook. Will take care of it manually.

Using machine_is_xxx() is not sufficient because there are 2 other
boards on same Platform/machine but with different values.

So, how to specify these parameters for the new board?

What do you mean by "board"?  If these are plugin modules for your
platform you need to either identify this at runtime and register a
different machine driver or select at compile time.

By board I mean a new development board. 

New board
sysclk = 24MHz
codec_name = "tlv320aic3x-codec.1-001b"

Previous Board
sysclk = 12MHz
.codec_name = "tlv320aic3x-codec.2-001b",

Both boards share the same machine is API (machine_is_am33xx()).

So, is there any mechanism/api to differentiate these 2 boards inside 
Code?

Has anyone else faced such situation?
