[sp] You can look at one of my patches on linux kernel to identify the
device capability for 600/720MHz.

[sp] The device comes up at 600MHz for now, but there is no limitation
on device to go all the way to 1GHz.

[sp] So, you are looking for common mechanism to go to highest supported
frequency. Right?
