* gpu: nvgpu: use platform data for ptimer source rateSeshendra Gadagottu2015-11-04
| | | | | | | | | | | | | | | | Instead of depending on clock frame-work, use platform data for ptimer source rate. Removed ptimerscaling10x platform data, and use ptimer source frequency to calculate ptimerscaling factor.
