omap_voltage_get_voltdata() - API to get the voltage table entry for a particular voltage : pointer to the VDD whose voltage table has to be searched : the voltage to be searched in the voltage table

This API searches through the voltage table for the required voltage domain and tries to find a matching entry for the passed voltage volt. If a matching entry is found volt_data is populated with that entry. This API searches only through the non-compensated voltages int the voltage table. Returns pointer to the voltage table entry corresponding to volt on success. Returns -ENODATA if no voltage table exisits for the passed voltage domain or if there is no matching entry.

voltdm_get_voltage() - Gets the current non-auto-compensated voltage : pointer to the voltdm for which current voltage info is needed

API to get the current non-auto-compensated voltage for a voltage domain. Returns 0 in case of error else returns the current voltage.

int voltdm_scale	(	struct voltagedomain *	voltdm,
		unsigned long	target_volt
	)

voltdm_scale() - API to scale voltage of a particular voltage domain. : pointer to the voltage domain which is to be scaled. : The target voltage of the voltage domain

This API should be called by the kernel to do the voltage scaling for a particular voltage domain during DVFS.
