Trying it on an igep com module (dm3730) i don't get the clk_set_rate
error (but there is no tvp hardware connected so i can't go farther).

So it must be something different between omap3430/omap3630 clocks, i
tried to use (CM_CAM_MCLK_HZ / 2) with the omap3530 one but i get the
same error.

I don't know what else i can try.
