omap4_dpll_regm4xen_recalc - compute DPLL rate, considering REGM4XEN bit : struct clk * of the DPLL to compute the rate for

Compute the output rate for the OMAP4 DPLL represented by . Takes the REGM4XEN bit into consideration, which is needed for the OMAP4 ABE DPLL. Returns the DPLL's output rate (before M-dividers) upon success, or 0 upon error.

		unsigned long	target_rate
	)

omap4_dpll_regm4xen_round_rate - round DPLL rate, considering REGM4XEN bit : struct clk * of the DPLL to round a rate for : the desired rate of the DPLL

Compute the rate that would be programmed into the DPLL hardware for if set_rate() were to be provided with the rate . Takes the REGM4XEN bit into consideration, which is needed for the OMAP4 ABE DPLL. Returns the rounded rate (before M-dividers) upon success, -EINVAL if is null or not a DPLL, or ~0 if an error occurred in omap2_dpll_round_rate().
