I have added under /sys/power:

• op_list_info: shows the CPU/DSP frequencies for all possible op states, so you don't have to use static values.
• op_dsp_range: interval of op values that op_dsp admits
• op_locked: 0 if op_dsp can be written to, 1 if it is locked.

I also have updated the DT packages, so you can count on those being present in any DT installation.
Don't assume that there will be just 4 op values. I want to try to add more op values (overclocking, underclocking) and if successful that number may change.
