That depends on what is left of clk.c after reorganization. >> How exactly is "clk_enable(BPWR_Clks[clkIdIndex].intClk)" less >> readable than "CLK_Enable(BPWR_Clks[clkIdIndex].intClk)" ? > > -- Did you check the argument of CLK_Enable function ?

If you see clk_enable there's nothing more to follow, so it's not hard to follow. Others explained why virtual clocks make sense, which would make the code even easier to follow. The only two places where clock functions are used are tiomap3430.c and tiomap3430_pwr.c. In tiomap3430.c, clk_enable functions can be used directly, there's no translation needed, and I already explained before, you can add debugging quite easily, so no need of clk.c for that. In tiomap3430_pwr.c the translation can happen in DSPPeripheralClkCtrl already, so again, no need of clk.c. If you reorganize the code this way the only thing left in clk.c would be clock initialization. I don't think it makes sense to keep one file for one small function which would be even smaller with virtual clocks.
